Attachment: solaris-hadoop.patch
> Capacity reporting incorrect on Solaris

> Key: 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?
> Index: src/java/org/apache/hadoop/fs/DF.java
