------------------------------

             Summary: TestHCM flaky: java.lang.IllegalArgumentException: Row length is 0
                 Key: HBASE-8145
                 URL: https://issues.apache.org/jira/browse/HBASE-8145
             Project: HBase
          Issue Type: Bug
          Components: test
    Affects Versions: 0.96.0
            Reporter: nkeywal
            Assignee: nkeywal
            Priority: Trivial
             Fix For: 0.96.0


I will check for 0.95.

{code}
    for (HRegion region : regions) {
      if (!region.getRegionInfo().getEncodedName().equals(toMove.getRegionInfo().getEncodedName())
          && Bytes.BYTES_COMPARATOR.compare(region.getRegionInfo().getStartKey(), ROW_X) < 0) {
        otherRow = region.getRegionInfo().getStartKey();
        break;
      }
    }
{code}

We're likely to get sometimes the startKey of the first region here, and that's an empty byte array. This make the put creation to fail, since there is now (with HBASE-8101) a check on the empty rows at put creation.
