----------------------------------------
Any update on this?Any fix?
> ZK connection leak
> ------------------
>
> Key: HBASE-5362
> URL: https://issues.apache.org/jira/browse/HBASE-5362
> Project: HBase
> Issue Type: Bug
> Components: mapreduce
> Affects Versions: 0.90.3
> Reporter: Ionut Ignatescu
>
> I have an application like a scheduler that starts periodically some MR jobs
> that reads from one HBase table and write in more tables, changing the row
> key and the columns list.
> I have encounted a problem with this: after each MR job, I have +1
> connections open to ZK and after a period of time, I have received
> IOException. I saw that I am not the first that had had this problem, but I
> didn't see any fix. No in HBase 0.90.4, nor in HBase 0.92.
> To fix this issue I wrote a custom TableInputFormat that forces to close the
> connection to ZK after each getSplits call.
> Also, the initTableMapperJob was overwritten.
> I found an open JIRA issue here:
> https://issues.apache.org/jira/browse/HBASE-3792
> Regards,
> Ionut I.
