What's the pros and cons to install HBase + Hadoop together vs. install HBase and Hadoop separately? -

-
i mean , 2 options : 1. install hbase on hadoop cluster offline computing, means 1 hadoop cluster. 2. install hadoop cluster offline computing , install hadoop cluster hbase use hdfs. so 2 options : 1 integrated cluster , 2 clusters. what's pros & cons these 2 options ? option 1: integrated cluster. pros: mapreduce reads or writes hbase more efficient data locality. cons: hbase region server reduce performance of machine (datanode , tasktracker) need hold cpu , memory. hbase latency may seconds if there many mapreduce jobs. if want make hbase response in time, need more work (for example, using memcache improve read performance). option 2: 2 clusters. prons: hbase region server not impact performance of hdfs datenode , tasktracker. cons: mapreduce needs read , write data remotely if wants access hbase. option needs more machines.

php - Codeigniter update record -

-
i have update record looks this $data_gallery = array( 'order' => $value ); $this->db->where('order', $neworder); $this->db->update('gallery', $data_gallery); i have say, 5 images have reorderd. have old position , new position. but loop through sometime overwrite each other. example: 5 images 1,2,3,4,5 i change order 2,1,3,4,5 i update in loop goes through array of new order. update order = 2 order = 1 update order = 1 order = 2 obviously second 1 never gets hit order = 2 no longer exits. i guess more logic question else. any ideas how can loop through , update without losing of data? though maybe updating in batch operation didn't far it. thanks in advance. use image's id in clause: $this->db->where('imageid', $imageid); this set new order each image without overwriting (and disappearing!) information.

java - More efficient method for storing records from a file -

-
recently in discussion asked: have one flat file containing many records 5 million. need write java program can fetch records file , store in database via jdbc. efficient approach? my suggestion create: one thread handle jdbc connection (additionally can make connection class singleton) another thread fetch records file & save in table. additionally when number of records saved in database, 100 commit first continue. here stored procedures better or there other way? sounds have right approach in mind. the cost , time spent on network i/o , db operations going larger file io , parsing time spent on flat file. there might small performance gain in having separate thread read file , prepare record db, wouldn't worth added complexity, , maybe not worth time jvm spend on thread management. i'd recommend: 1 thread read file , submit db updates. as bitfiddler says, use preparedstatements batch updates ( preparedstatement.addbatch() ) every record,

jquery - Best way to build a "select all" checkbox -

-
i have "select all" checkbox(a) , others related it(b). i hope: when a's checked or not, make of b same a. when of b's checked, make a's checked. when not of b's checked,make a's not checked. using jquery preferred, but there better way coming html5? like: <checkbox id="target" name="select all"/> <checkbox relatetd="target" name="1"/> <checkbox relatetd="target" name="2"/> or xpath if have many subgroups different dom structures: <checkbox id="target" name="select all"/> <div> <checkbox relatetd="../" name="1"/> <checkbox relatetd="../" name="2"/> </div> <checkbox id="target2" name="select all"/> <div> <div> <checkbox relatetd="../../" name="1"/> <checkbox relatetd=".

How to prevent 3 nested MySQL queries from timing out -

-
i want delete records in t3 field names in t2 missing, if meet record id t1. the query t1: select max(id) t1 name1 = "xxx" , user_id = '$id' works fine. the t2 query: select name2 t2 record in (select max(id) t1 name1 = "xxx" , user_id = '$id') also works fine, takes while. but t3 query: delete t3 name3 not in (select name2 t2 record in (select max(id) t1 name1 = "xxx" , user_id = '$id')); results in "#2006 - mysql server has gone away" how query result within reasonable time? i think can use join queries instead? select name2, max(t1.id) t2 inner join t1 on t2.t1_id = t1.id name1="xxx" , user_id='$id'

c - MPI communicate large two dimensional arrays -

-
related previous question concerning copying of 2- 1-dimensional arrays, wondered if there better way whole business, try achieve. so, want mpi communicated couple of large 2 dimensional arrays (which allocated dynamically arrays of arrays, known size @ compile time) master clients , vice versa. data supposed scattered to/gathered clients column-wise. what doing @ moment map 2-dimensional arrays (which in fact sub-arrays of 3-dimensional ones) statically allocated 1-dimensional arrays, send these 1-dim. arrays via mpi , rebuild 2-dimensional arrays again @ receiver. however, have feeling there should (much) more efficient that... thanks lot! c99 has support dynamic multidimensional arrays: using them can avoid copy data @ all. example following code compile gcc -std=c99 : #include <stdio.h> #include <stdlib.h> int main(int argc, char **argv) { int m = atoi(argv[1]); int n = atoi(argv[2]); int p = atoi(argv[3]); // if defined in stack... i'm

ios - uitableview cell value not refresh according with the ones in coredata after change -

i'm building master-detail application, saying master view a(tableview), second-view(tableview) b, detail-view c. data core-data. in secondview(tableview), popover prompt cell value change when user tap specific cell. after change on popover screen, dismiss popover, return secondview(tableview) , update core data accordingly. , cell value expected reflect update value. issue doesn't work that. cell value still remains old ones, though core data update new value(i confirmed via nslog in method --tableview:cellforrowatindexpath. print cell's new value, display cell's old value). tried put table-view:reloaddata viewwillappear , popovercontrollerdiddismisspopover method, still doesn't work. i cannot figure out it. cell value on secondview(tableview) update after return view master-view , again switch second-view b. however, second view reflect new cell addition immediately, addition via popover prompt cell new value input. would please this? thanks. -(voi

javascript - How to create duplicate object -

-
Image
i have object nested objects in following way. var g = { "steps": [{ "location": [{ "a": "1" }, { "a": "2" }] }] }; i created duplicate object using object in following way. var h=object.create(g); the problem was,if modify in h , g reflecting.how can prevent this.i tried underscore function( clone ). modified: h["steps"][0]["location"][0]["a"]="3" after modify: g looks like h looks like even if modify in h , g should not reflect. can me. thanks. as per _.clone docs, create shallow-copied clone of object. nested objects or arrays copied reference, not duplicated. shallow copied objects tend show problem experiencing now. if object use doesn't have methods/variables attached it , can this var h = json.parse(json.stringify(g)); this deep copy. note: if object has c

Javascript setTimeOut in For Loop Behaviour -

-
i curious why , how javascript interpreter outputs following 5 5 5 5 5 when running code: for(var i=0;i<5;i++){ settimeout(function(){console.log(i);},200); }; can provide thorough explanation? it's chronology. remember timeout synchronous operation delayed, time runs, consults i , finds value 5. because last action of (synchronous) loop set value 5: reached 4 (the last iteration of loop) , i++ made 5. if want output 0-4 retain timeout, need capture current, iterative value of i @ time create timeout. can passing immediately-executing function: for(var i=0;i<5;i++) settimeout((function(i) { return function(){ console.log(i); }; })(i),200);

matlab array create random consecutive ones -

-
i create 4-dimensional array random number of consecutive ones in each row. ones should start in first column , end in random column. example: array(:,:,1,1) = [ 1 1 1 0 0 0; 1 1 0 0 0 0; 1 1 1 1 1 0; ... ] one 3 loops inefficient: array = zeros(n,n,n,n); i= 1:n j = 1:n k =1:n rows = ceil(n*rand()); array(k,1:rows,j,i) = 1; end end end can find better solution? thanks!! simple , straight-up approach (might not random though) rows = 8; %%// number of rows cols = 7; %%// number of columns ch3 = 3; %%// number of elements in 3rd dimension ch4 = 2; %%// number of elements in 4th dimension array = sort(round(rand(rows,cols,ch3,ch4)),2,'descend') bsxfun approach (much faster shown in benchmark results below , random) %%// sizes rows = 8; %%// number of rows cols = 7; %%// number of columns ch3 = 3; %%// number of elements in 3rd dimension ch4 = 2; %%// numb
