Subject [jira] Commented: (HADOOP-2855) [HOD] HOD fails to allocate a cluster if the tarball specified is a relative path
Date Wed, 26 Mar 2008 11:57:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2855?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12582253#action_12582253
] 

Hemanth Yamijala commented on HADOOP-2855:
------------------------------------------

Code and tests looks good. Works with relative paths correctly.

Could we have added a test for checking relative path expansion, that normalization actually
expands the relative path ? Maybe create a tmp file in the current directory (which is the
original directory), chdir to /tmp, normalize, verify that the tmp file is normalized to the
full path in the original directory, then chdir back to the original directory. Would that
work ?

Apart from this, +1.

> 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.
