----------------------------------
Assignee: Jimmy Xiang
> Performance regression caused by HBASE-4054
> -------------------------------------------
>
> Key: HBASE-6471
> URL: https://issues.apache.org/jira/browse/HBASE-6471
> Project: HBase
> Issue Type: Bug
> Components: client
> Affects Versions: 0.92.0
> Reporter: Lars George
> Assignee: Jimmy Xiang
> Priority: Critical
> Fix For: 0.94.2
>
> Attachments: trunk-6471.patch
>
>
> The patch in HBASE-4054 switches the PooledHTable to extend HTable as opposed
> to implement HTableInterface.
> Since HTable does not have an empty constructor, the patch added a call to
> the super() constructor, which though does trigger the ZooKeeper and META
> scan, causing a considerable delay.
> With multiple threads using the pool in parallel, the first thread is holding
> up all the subsequent ones, in effect it negates the whole reason we have a
> HTable pool.
> We should complete HBASE-5728, or alternatively add a protected, empty
> constructor the HTable. I am +1 for the former.
