Stefan Seelmann updated HBASE-4417:
-----------------------------------

    Attachment: HBASE-4417-0.92.diff
                HBASE-4417-0.90.diff

Patches for 0.90 (branch) and 0.92 (trunk).

When running the testcase included in the patch without the patched HBaseAdmin 
class a "netstat | grep 21818 | grep ESTABLISHED" shows that ZooKeeper 
connections are not closed. Additionally the 1000 time loop opens too many 
ZooKeeper connections that the test fails.

> HBaseAdmin.checkHBaseAvailable() doesn't close ZooKeeper connections

> HBaseAdmin.checkHBaseAvailable(conf) clones the passed connection, later in 
> HBaseAdmin constructor the connection is cloned again. Thus a new HConnection 
> object with ZooKeeper connections is created.
