[jira] Updated: (HADOOP-2855) [HOD] HOD fails to allocate a cluster if the tarball specified is a relative path

["Vinod Kumar Vavilapalli (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-2855?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vinod Kumar Vavilapalli updated HADOOP-2855:
--------------------------------------------

    Attachment: HADOOP-2855

Earlier behavior was not to normalize any paths(files or directories), so relative paths weren't getting expanded. Changed that behavior now. Tested with relative paths for ringmaster.hadoop-tar-ball, hod.script and hod.clusterdir.

Also added a new data type uri. Ringmaster.hadoop-tar-ball is changed to be of this data type.  So, a URI of the format file:// can be used to denote a path on the local file system. hodring.log-destination-uri also needs to changed to use this data type. Will file a jira for that.

Attaching patch.

> Run hod -t my-tar.tar.gz -o "allocate hod-cluster 3". Ringmaster fails to come up. The log shows the exception as an invalid URL for the tarball file. Basically HOD should translate the relative path to an absolute path and send it to the ringmaster.
