TestMergeTool is too sensitive to hanging HBase cluster from other test
-----------------------------------------------------------------------

                 Key: HBASE-4264
                 URL: https://issues.apache.org/jira/browse/HBASE-4264
             Project: HBase
          Issue Type: Bug
            Reporter: Ted Yu


The TestMergeTool.testMergeTool failure in build 2154 was due to the following check:
{noformat}
      HBaseAdmin.checkHBaseAvailable(getConf());
      LOG.fatal("HBase cluster must be off-line.");
{noformat}
HBase cluster from some other test(s) was hanging since "merging regions 0 and 1" is the first merge.
The test can be made more robust by calling HBaseAdmin.shutdown() before making the first merge.

In Merge.java, -1 is returned in 5 places. I think we should return different values so that it is more obvious what the cause was.
