can explain number of partitions created spark dataframe. i know rdd, while creating can mention number of partitions below. val rdd1 = sc.textfile("path" , 6) but spark dataframe while creating looks not have option specify number of partitions rdd. only possibility think is, after creating dataframe can use repartition api. df.repartition(4) so can please let me know if can specify number of partitions while creating dataframe. you cannot, or @ least not in general case not different compared rdd. example textfile example code you've provides sets limit on minimum number of partitions . in general: datasets generated locally using methods range or todf on local collection use spark.default.parallelism . datasets created rdd inherit number of partitions parent. datsets created using data source api: in spark 1.x typically depends on hadoop configuration (min / max split size). in spark 2.x there spark sql specific configuratio...

i've completed newsreader app, works => hurray, apart internet checks. when device not connected internet, app doesn't notify user fact. i have internet check working, want connect every single request, app doesn't break if connection go down while using it. i kind of new async way of doing things in ionic, , have straight question: there way make sure device connected internet before executing request? believe me, i've tried interceptors, , can't seem work. the idea this: if app finds out, device not connected internet (wi-fi turned off, or mobile data turned off, whole extent of internet check), uses $ionicpopup notify user. 2 buttons: "refresh", "close". upon clicking "refresh", internet check performed again, until connection on. during time, request held. clicking "close" closes dialog , request gets rejected ( .reject() ). a perfect solution while() loop , blocking $ionicpopup , $ionicpopup love asynchr...

i've got set of specflow tests i'm running , i'm trying write results far file after each scenario finishes, , write again @ end of entire test run. if run tests in debug mode code hit after each scenario, file appears in windows explorer after tests finish (or force tests stop). code below, writes file in separate project specflow test project. i not flushing , had in place of streamwriter: using (var file = new fileinfo(filepath).appendtext()) but wasn't working, after looking various examples on internet added flush, close, process.start, changed streamwriter , none of them helped. current code still isn't working is: private string rootfolderpath = directory.getparent(@"..\..\..\..") +@"\"; public void writealltestscenarionames(list<scenarioresult> results, string filename, string directoryname) { results.sort(); directory.createdirectory(rootfolderpath + directoryname); string filepath = ...

let me explain actual problem. have template string this: /${name} post /{id} /file-content post the indentation has remain untouched. now if use such template string might this: function test(arr) { let ret = [] arr.foreach( function(name) { return `/${name} post /{id} /file-content post` return ret } ) } looks pretty ridiculous, right? of course put spaces template match code indentation, i'd have perform unnecessary operations on string afterwards normalize again. so idea move template string external file , require file whenever need template string. require can't used problem because it's nothing more text file , don't want read file disk every time need , perform eval on it. i think of several workarounds problem, cannot seem find satisfying solution. how this: // template.js module.exports = name => ` /${name} post /{id...

i'm serving static html, , want them sent client without <!-- comment --> comments, can compromise security. is there way this? something similar razor's @* comment *@ html... you write comments in between razor's comment tags instead of html comment tags. won't visible on front-end. besides this, printing put in html file text (server-side scripts razor , php excluded). there no way take comments out of static html unless minify them on server through tool. since state static html pages, i'm guessing aren't using tools @ all? you use tools http://www.willpeavy.com/minifier/ , example. the security risks of leaving comments in shouldn't bad. shouldn't putting valuable information in html comments in first place. nowadays used showing element starts and/or ends when other programmers take over. your javascript visible on website well. let's work ajax calls , database. create more risk html comments. obviously, have ma...

is there configuration in kubernetes in can specify minimum number of requests queued before new instance gets spawned? this context: have got powerful high cpu machines set our use case , every request levies high amount of load on server. works perfect until reach specific number say... 300 requests ramp-up time of 100 milliseconds. , point receiving connection refused error time , server starts handle them once new machine spawned. best way handle load spikes? looking "pending latency" config in app engine. application deployed on google compute engine , orchestrated kubernetes. you can use readinessprobe (see container probes ) indicate container ready service requests, , use horizontalpodautoscaler automatically scale apps up/down based on observed cpu utilization. hope helps.
