INLINE COMMENTS
src/main/java/org/apache/hadoop/hbase/MiniZooKeeperCluster.java:64 How was
0xc000 chosen ?
src/main/java/org/apache/hadoop/hbase/MiniZooKeeperCluster.java:113 Should
this be debug ?
I imagine there would be many mini zookeeper clusters running in parallel on
the build machine.
src/main/java/org/apache/hadoop/hbase/client/HTable.java:90 Nice.
We can mark this ctor deprecated in HBase 0.92.
For HBase TRUNK, I think we should remove this ctor and the ctor on line 104.

>
> Key: HBASE-4746

>
> The hard-coded ZK client port has long been a problem for running HBase test
> suite in parallel. The mini ZK cluster should run on a random free port, and
> that port should be passed to all parts of the unit tests that need to talk
> to the mini cluster. In fact, randomizing the port exposes a lot of places in
> the code where a new configuration is instantiated, and as a result the
> client tries to talk to the default ZK client port and times out.
> The initial fix is for 0.89-fb, where it already allows to run unit tests in
> parallel in 10 minutes. A fix for the trunk will follow.
