             Summary: TestHBCKCommandLineParsing#testCommandWithOptions hangs on call to HBCK2#checkHBCKSupport
                 Key: HBASE-21353
                 URL: https://issues.apache.org/jira/browse/HBASE-21353
             Project: HBase
          Issue Type: Test
            Reporter: Ted Yu


I noticed the following when running TestHBCKCommandLineParsing#testCommandWithOptions :

{code}
The test doesn't spin up hbase cluster.
Hence the call to check hbck support hangs.

In HBCK2#run, we can refactor the code such that argument parsing is done prior to calling HBCK2#checkHBCKSupport .
