Subject [jira] Resolved: (MAPREDUCE-978) -file option in streaming does not preserve execute permissions
Date Wed, 23 Jun 2010 05:40:50 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-978?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amareshwari Sriramadasu resolved MAPREDUCE-978.
-----------------------------------------------

    Resolution: Invalid

Files passed using -file option are packaged into a jar and unjarred on the computing node.
So, it wont preserve the execute permissions on the file.

> For a streaming application I used the -file option to move some executable files to
the slave nodes.  On the submit node, they had +x permissions but on the destination node
they were created with -x permissions.  This probably has to do with the umask settings on
the various nodes, but streaming should preserve the original permissions.
