Subject [jira] [Commented] (YARN-6060) Linux container executor fails to run container on directories mounted as noexec
Date Sat, 07 Jan 2017 03:43:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-6060?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15806672#comment-15806672
] 

Miklos Szegedi commented on YARN-6060:
--------------------------------------

Thank you, [~aw]. Please, remember, I still have the {{#ifdef __linux}} set. However, I have
to refer to this code again:
{code}
    public UnixShellScriptBuilder(){
      line("#!/bin/bash");
      line();
    }
{code}
Do we have a bug in the existing code in this case? Is this what you meant by mentioning pkgsrc?
I am assuming this could help there:
{code}
    public UnixShellScriptBuilder(){
      line("#!/usr/bin/env bash");
      line();
    }
{code}
