Ken Weiner updated HBASE-1762:
------------------------------
Attachment: HBASE-1762.patch
> Remove concept of ZooKeeper from HConnection interface
> ------------------------------------------------------
>
> Key: HBASE-1762
> URL: https://issues.apache.org/jira/browse/HBASE-1762
> Project: Hadoop HBase
> Issue Type: Improvement
> Components: client
> Affects Versions: 0.20.0
> Reporter: Ken Weiner
> Attachments: HBASE-1762.patch
>
>
> The concept of ZooKeeper is really an implementation detail and should not be
> exposed in the {{HConnection}} interface. Therefore, I suggest removing the
> {{HConnection.getZooKeeperWrapper()}} method from the interface.
> I couldn't find any uses of this method within the HBase code base except for
> in one of the unit tests: {{org.apache.hadoop.hbase.TestZooKeeper}}. This
> unit test should be changed to instantiate the implementation of
> {{HConnection}} directly, allowing it to use the {{getZooKeeperWrapper()}}
> method. This requires making
> {{org.apache.hadoop.hbase.client.HConnectionManager.TableServers}} public.
> (I actually think TableServers should be moved out into an outer class, but
> in the spirit of small patches, I'll refrain from suggesting that in this
> issue).
> I'll attach a patch for:
> # The removal of {{HConnection.getZooKeeperWrapper()}}
> # Change of {{TableServers}} class from private to public
> # Direct instantiation of {{TableServers}} within {{TestZooKeeper}}.
