Subject [jira] Resolved: (HADOOP-3004) HOD allocate command does not accept '~'
Date Wed, 12 Mar 2008 05:10:46 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-3004?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hemanth Yamijala resolved HADOOP-3004.
--------------------------------------

    Resolution: Invalid

I see the issue. Basically hod isn't doing anything with respect to normalizing ~/clusterdir
to /home/user/clusterdir. It relies on the shell to do it. When we specify an option as --hod.clusterdir=~/clusterdir,
the shell is not expanding it, while it is, when we specify it as --hod.clusterdir ~/clusterdir.
And this not just with hod. Try the same with standard linux commands like tar, cp etc. For
e.g. cp --target-directory=~/abc doesn't work while cp --target-directory ~/abc does.

So, closing this as not a bug.
