Subject [jira] [Commented] (YARN-1303) Allow multiple commands separating with ";" in distributed-shell
Date Wed, 23 Oct 2013 20:31:47 GMT

    [ https://issues.apache.org/jira/browse/YARN-1303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13803289#comment-13803289

Hitesh Shah commented on YARN-1303:
-----------------------------------

[~xgong] Have you looked at fixing the underlying issue of passing the args correctly from
the client to the AM? At the moment, they are sent via the AM's command line which can create
problems. To pass to the AM via command-line requires correct escaping based on type of OS.
Or, they could be passed in through a file which would hide away such aspects.

> In shell, we can do "ls; ls" to run 2 commands at once. 
> In distributed shell, this is not working. We should improve to allow this to occur.
There are practical use cases that I know of to run multiple commands or to set environment
variables before a command.
