Subject [jira] [Commented] (HDFS-6073) NameNodeResourceChecker prints 'null' mount point to the log
Date Fri, 04 Apr 2014 05:43:15 GMT

Uma Maheswara Rao G commented on HDFS-6073:
-------------------------------------------

Thanks a lot, Akira for patch!
Patch almost looks good except the concern that, your test is on NamenodeResourceChecker,
But bug exist in DF.   We could have written test directly on DF itself, no?
That will also make the code changes only in common now. So we could move this JIRA to common
and update the JIRA title and description?

> If the available space on the volume used for saving fsimage is less than 100MB (default),
NameNodeResourceChecker prints the log as follows:
> {code}
> Space available on volume 'null' is 92274688, which is below the configured reserved
amount 104857600
> {code}
> It should print an appropriate mount point instead of null.
