Fix Version/s: (was: 0.90.0)
Moving out minor issue.
> Req/sec in web UIs are way off when regions are moving
> ------------------------------------------------------
>
> Key: HBASE-2883
> URL: https://issues.apache.org/jira/browse/HBASE-2883
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.20.5, 0.89.20100621
> Reporter: Jean-Daniel Cryans
> Priority: Minor
>
> Now that the region servers can heartbeat back to the master as soon as they
> have a message (region open, close, etc), they also recompute their metrics.
> I see two problems:
> - The metrics are recomputed way too often, and by the looks of that code it
> seems quite intense.
> - Our UIs are expecting that the value returned by the metrics computation
> is per second, but when regions are moving a RS can ping back a few times
> within a single second. This gives a very wrong view of the load.
> I think it's time we move metrics computation in it's own separate thread.
