Subject [jira] [Commented] (YARN-1303) Allow multiple commands separating with ;
Date Tue, 15 Oct 2013 21:59:42 GMT

    [ https://issues.apache.org/jira/browse/YARN-1303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13795708#comment-13795708

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

[~xgong] Could you clarify why "ls;ls" or "ls | grep foo" does not work in the first place?
Is there a bug in the implementation that needs to be fixed to address this basic functionality?

> 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.
