obviously need start zookeeper server on 1 of cluster machines, need other client machines connect server. way did used ssh connect headnode, found zk server running on port 2181. so, used ifconfig machine's ip address (for example 10.0.0.8) , had worker nodes connect to: 10.0.0.8:2181. however, mr job completes works , output not correct. suspect i'm doing wrong zookeeper, didn't follow tutorial , improvised steps. hdinsight has multiple zookeeper servers. not sure if specifying 1 might cause of problem seeing. i wrote example while uses storm write hbase (both servers on same azure virtual network,) , part of configuration, had specify 3 zookeeper servers component writes hbase. ( https://azure.microsoft.com/en-us/documentation/articles/hdinsight-storm-sensor-data-analysis/ article.) from cluster head node, can ping zookeeper0, zookeeper1, , zookeeper2 find ip address of each.

i need set environment variables in python script , want other scripts called python (shell scripts) child process see environment variables set. value number. if os.environ["debussy"] = 1 , complains saying 1 has string. want know how read environment variables in python (in later part of script) once set it. environment variables must strings, use os.environ["debussy"] = "1" to set variable debussy string 1 . access variable later, use print os.environ["debussy"] child processes automatically inherit environment of parent process -- no special action on part required.

i'm optimizing more complex code, got stuck problem. a<-array(sample(c(1:10),100,replace=true),c(10,10)) m<-array(sample(c(1:10),100,replace=true),c(10,10)) f<-array(sample(c(1:10),100,replace=true),c(10,10)) g<-array(na,c(10,10)) i need use values in & m index f , assign value f g i.e. g[1,1]<-f[a[1,1],m[1,1]] except indexes, , optimally/fast possible i make loop me seems rather dumb , slow. seems should able in apply family, i've had no luck figuring out how that. need keep data structured here can use matrix operations in different parts of code. i've been searching answer haven't found particularly helpful yet. g[] <- f[cbind(c(a), c(m))] this takes advantage of fact matrices can addressed vectors , using matrix index.

a kml file include in project parses correctly whereas same file downloaded server not?! i modified apple's kml parsing example parse kml file. if add kml file directly xcode project parses correctly , displays it's polylines, annotations, etc. on map expected. if download same kml file server, save disk , attempt parse it, parsing not work. i.e. parser not find elements parse in file nothing displayed on map! firstly have verified file downloads , saves disk correctly. checked simulator's data ( simpholders handy tool this) file , compare original 1 in case of corruption, no problem there, downloads , saves correctly, no corruption. i next checked url file pass kml parser ensure correct , fine. used nsfilemanager fileexistsatpath determine this, kml file @ path provide parser. in map view controller's viewdidload method download file server , pass parser. - (void)viewdidload { [super viewdidload]; [[kmldownloader sharedkmldownloader] downloadf...

suppose there deterministic turing machine, e.g. 1 runs in polynomial time, , decides language l. does automatically means decides l's complement language? when saying l's complement language, of course mean language k, such that: k = {x : x not in l} suppose have deterministic turing machine bounded running time, can build turing machine accepts complement of l reversing answer. however, requires turing machine stop on every input (which case if decides language l , stops on every input). machine not decider complement of l, because decider of language has accept it. in general case machine merely accepts (only has stop on inputs "yes"-answers) not decides (stops on every input) language l endless loop inputs not in l, therefore there possibly no explicit "no"-answer reversed.

i'm trying write javascript function calls dosomething() continuously, long some_condition true. if some_condition becomes false, should check after 5 seconds whether some_condition has again become true, , if not, display error message on screen. i have of function written, confused whether doing correctly. help. while (some_condition) { dosomething(); else { ??? } no, should not use while loop. javascript single threaded, , if have while loop never returns, browser (or javascript environment of choice) become unresponsive. you need use settimeout schedule function. function enqueuesomething() { if (some_condition) dosomething(); // enqueue ourselves run again without blocking thread of execution settimeout(enqueuesomething); else // wait 5 seconds, try again settimeout(enqueuesomething, 5000); } you'll need maintain state indicates whether you've waiting 5 seconds, , add error-alerting code.

i have app in qt 5.4 when need include new functionality, need recompile app, take time, need know how create or modified app use plugins created me. a plugin-based architecture requires binary compatible , stable interfaces. once have these, full-project recompilation should take time recompiling single plugin. most likely, have interdependencies in code preclude maintaining binary compatibility anyway - if didn't, changes localized enough recompilation touch couple of files. what you're trying come solution wrong problem. fix structure of code, , recompilation times drop. no need plugins.

have kinda weird here. have database that's called fldoc. in has column called sentence contains 7 numbers represent length of time. example: 0050000 0750000 0000600 0040615 0000110 in 7 digits length of type since digits represent yyymmdd so i'd script can convert this: 5y 00m 00d 75y 00m 00d 6m (or 000y 6m 00d fine well) 4y 6m 15d etc etc thanks in advance... concat new sql server 2012. if have previous version of sql server, instead achieve desired output: select sentence ,( case when cast(left(sentence, 3) int) > 0 cast(cast(left(sentence, 3) int) varchar(3)) + 'y ' else cast(left(sentence, 3) varchar(3)) + 'y ' end + case when cast(substring(sentence, 4, 2) int) > 0 cast(cast(substring(sentence, 4, 2) int) varchar(2)) + 'm ' else cast(substring(sentence, 4, 2) varchar(2)) + 'm ' end +...
