[jira] [Commented] (MAPREDUCE-50) NPE in heartbeat when the configured topology script doesn't exist

["Andrew Liles (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAPREDUCE-50?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13993529#comment-13993529 ] 

Andrew Liles commented on MAPREDUCE-50:
---------------------------------------

To help others who encounter this:

This problem can occur where the "<myPath>/topologyProgram" cannot be executed not because the script does not exist, but because of an operating system restriction.  

In the case of a standard Ubuntu Server, this prohibits execution on the /run mount point.  Simply solved by executing:
sudo mount -o remount,exec /run

See https://groups.google.com/a/cloudera.org/forum/#!msg/scm-users/mDlnpWSfXMI/39cDl2C7gSUJ

Cloudera install should detect and warn/remedy this.  But that's another ticket...
