Capacity reporting incorrect on Solaris
---------------------------------------
Key: HADOOP-6319
URL: https://issues.apache.org/jira/browse/HADOOP-6319
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 0.20.1
Reporter: Doug Judd
Attachments: solaris-hadoop.patch
When trying to get Hadoop up and running on Solaris on a ZFS filesystem, I
encountered a problem where the capacity reported was zero:
Configured Capacity: 0 (0 KB)
It looks like the problem is with the 'df' output:
$ df -k /data/hadoop
Filesystem 1024-blocks Used Available Capacity Mounted on
/ 0 7186354 20490274 26% /
The following patch (applied to trunk) fixes the problem. Though the real
problem is with 'df', I suspect the patch is harmless enough to include?
