scala - hadoop distcp doesnot create folder when we pass single file -


i facing below issues in hadoop distcp suggestion or highly appreciated.

i trying copy data google cloud platform amazon s3

1) when have multiple files copy source destination (this work fine)

  val sourcefile : string = "gs://xxxx_-abc_account2621/abc_account2621_click_20170616*.csv.gz [multiple files copy (we have * in file name)]    output: s3://s3bucketname/xxx/xxxx/clientid=account2621/date=2017-08-18/   files in above path   abc_account2621_click_2017061612_20170617_005852_572560033.csv.gz   abc_account2621_click_2017061616_20170617_045654_572608350.csv.gz   abc_account2621_click_2017061622_20170617_103107_572684922.csv.gz   abc_account2621_click_2017061623_20170617_120235_572705834.csv.gz

2) when have 1 file copy source destination (issue)

    val sourcefile : string = "gs://xxxx_-abc_account2621/abc_account2621_activity_20170618_20170619_034412_573362513.csv.gz     output:s3://s3bucketname/xxx/xxxx/clientid=account2621/     files in above path     date=2017-08-18 (directory replace file content , doesn't have file type)

code:

 def main(args: array[string]): unit = {   val array(environment,customer, typesoftables, clientid, filedate) = args.take(5)   val s3path: string = customer + "/" + typesoftables + "/" + "clientid=" + clientid + "/" + "date=" + filedate + "/"   val sourcefile : string = "gs://xxxx_-abc_account2621//abc_account2621_activity_20170618_20170619_034412_573362513.csv.gz"   val destination: string = "s3n://s3bucketname/" + s3path   println(sourcefile)  println(destination)   val filepaths: array[string] = array(sourcefile, destination)     executedistcp(filepaths)   }   def executedistcp(filepaths : array[string]) { val conf: configuration = new configuration()  conf.set("fs.gs.impl", "com.google.cloud.hadoop.fs.gcs.googlehadoopfilesystem") conf.set("fs.abstractfilesystem.gs.impl","com.google.cloud.hadoop.fs.gcs.googlehadoopfs") conf.set("google.cloud.auth.service.account.enable", "true") conf.set("fs.gs.project.id", "xxxx-xxxx") conf.set("google.cloud.auth.service.account.json.keyfile","/tmp/xxxxx.json") conf.set("fs.s3n.awsaccesskeyid", "xxxxxxxxxxxx") conf.set("fs.s3n.awssecretaccesskey","xxxxxxxxxxxxxx")     conf.set("mapreduce.application.classpath","$hadoop_mapred_home/share/hadoop/mapreduce/*,$hadoop_mapred_home/share/hadoop/mapreduce/lib/* ,/usr/lib/hadoop-lzo/lib/*,/usr/share/aws/emr/emrfs/conf,/usr/share/aws/emr/emrfs/lib/*,/usr/share/aws/emr/emrfs/auxlib/*,/usr/share/aws/emr/lib/*,/usr/share/aws/emr/ddb/lib/emr-ddb-hadoop.jar,/usr/share/aws/emr/goodies/lib/emr-hadoop-goodies.jar,/usr/share/aws/emr/cloudwatch-sink/lib/*,/usr/share/aws/aws-java-sdk/*,/tmp/gcs-connector-latest-hadoop2.jar") conf.set("hadoop_classpath","$hadoop_classpath:/tmp/gcs-connector-latest-hadoop2.jar")   val outputdir: path = new path(filepaths(1)) outputdir.getfilesystem(conf).delete(outputdir, true)  val distcp: distcp = new distcp(conf,null) toolrunner.run(distcp, filepaths)  } }

by adding below code above issue fixed

code 

 val makedir: path = new path(filepaths(1))  makedir.getfilesystem(conf).mkdirs(makedir)

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
