Using Hadoop through a SOCKS proxy? -


Then our Hadoop cluster runs on some nodes and can only be reached from these nodes. You do SSH and your work.

Since it is quite upset, but (obviously) nobody will be able to go to try to configure access control so that it is useful for some outside, I try the next best thing Use SSH to run a sock proxy in the cluster, i.e.: 

  $ ssh -D localhost: 10000 the.gateway cat

There are whispers of SOCKS support (naturally I have not received any document), and go Ira as it core-site.xml : 

  & lt; Property & gt; & Lt; Name & gt; Fs.default.name & lt; / Name & gt; & Lt; Price & gt; HDFS: //reachable.from.behind.proxy: 1234 / & lt; / Value & gt; & Lt; / Property & gt; & Lt; Property & gt; & Lt; Name & gt; Mapred.job.tracker & lt; / Name & gt; & Lt; Price & gt; Reachable.from.behind.proxy: 5678 & lt; / Value & gt; & Lt; / Property & gt; & Lt; Property & gt; & Lt; Name & gt; Hadoop.rpc.socket.factory.class.default & lt; / Name & gt; & Lt; Price & gt; Org.apache.hadoop.net.SocksSocketFactory & lt; / Value & gt; & Lt; / Property & gt; & Lt; Property & gt; & Lt; Name & gt; Hadoop.socks.server & lt; / Name & gt; & Lt; Price & gt; Local Host: 10000 & lt; / Value & gt; & Lt; / Property & gt;  
  
  
  
  
  
  
 < / P> 
 
 I am just trying to run jobs, not administering cluster. I only need to access HDFS and deposit jobs through SDOS (SOCS) through SOCS (It seems that there is a completely different thing about using SSL / proxy between cluster nodes etc.; It should not be that my machine is not part of a cluster, just a customer.)  
 Is there any useful document on that? To illustrate my failure to do something useful: I am through  strace -f . We found the configuration value by running the client and examining the configuration files to be read. 
 
 Out of which is the description of the configuration value, even its response? (I've got a really void reference document, just a different old tutorial, I hope I'm missing something?) 
 
 Is there really any way to dump the configuration value that it uses? is?

The original code for this to be applied was added to

but this article Also notes that you have to change the socket class with socks

with

& lt; Property & gt; & Lt; Name & gt; Hadoop.rpc.socket.factory.class.default & lt; / Name & gt; & Lt; Price & gt; Org.apache.hadoop.net.SocksSocketFactory & lt; / Pricing & gt; & Lt; / Property & gt; Edit: Note that the properties are in different files:

  1. fs.default.name and hadoop.socks.server and hadoop.rpc.socket Factory.class.default is cor- site.xml
  2. mapped. JobTracker and Mapped Job Tractor. Mapred-site.xml (config for map-less)
need to go to HTTP.addressconfig

sqlite3 - UPDATE a table from the SELECT of another one -

I have the first table article where some data is missing. In the table, articles_tmp I have a part of the missing data. So I want to update the articles. Where the path path is data in articles_tmp.path where the path is not zero . With SQLite , it does not work: update article SET path = (SELECT at.path FROM Articles_tmp as AS, WHERE at.article_id = a.id and a.asp, the text is in the form and not on. It has been transmitted) where the path is null MS Access Along with, it works fine: Update Articles Join the Inner Articles at articles_tmp articles.id = articles_tmp.id SETP articles.path = articles_tmp.path Can anyone help? Sin CE SQL Server Syntax, which I provided, was not working, here this solution With whom I have come. A little modification of your original query, but with my "correlation" suggestion added. There is a SQL Bella for this: Here is the code: update article SET path = (SELECT path from articles_tmp AS T WHERE t.id

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ

javascript - Render HTML after each iteration in loop -

I'm trying to gradually increase the font size of text on a web page. The code works in my place, although the new HTML / CSS does not render after every iteration of the loop and when all this is done, then display only the text of 100 px size. To see the text as if it is slowly zooming, I need to do this JavaScript is down because it is being used from a different file here is what I have ... < Pre> & lt; P class = "game-title" style = "font-size: 50px" & gt; Test & lt; / P & gt; Function sleep (milliseconds) {var start = new date ().
