Subject [jira] [Commented] (ACCUMULO-2184) "Unknown" HDFS usage on monitor
Date Mon, 13 Jan 2014 20:54:51 GMT


Josh Elser commented on ACCUMULO-2184:

bq. I thought we were getting rid of that box?


bq. I think you're thinking of ACCUMULO-873


Namenode/Jobtracker boxes are gone -- Master box is not. Master box calls out to HDFS to get
FS usage amounts which is what this issue was fixing.

>             Project: Accumulo
>          Issue Type: Bug
>          Components: monitor
>    Affects Versions: 1.4.0, 1.4.1, 1.4.2, 1.4.3, 1.4.4, 1.5.0
>            Reporter: Josh Elser

>             Fix For: 1.4.5, 1.5.1, 1.6.0
> When running Accumulo as *not* a member of the HDFS superuser group (or the superuser,
itself), the monitor cannot get a ContentSummary for all of HDFS.
> It can, however, get a ContentSummary for just {{instance.dfs.dir}} and show the disk
usage of Accumulo, even if not relative to HDFS total used/available.
> The code currently gets that ContentSummary for {{instance.dfs.dir}} but doesn't assign
it to the local variable until after it tries to do the same for {{/}}, which it fails on.
