[hbck]: hbck -metaonly incorrectly reports inconsistent regions after HBASE-9698 fix

    Details

    • Type: Bug

      Description

      In my testing, I found that this call began to fail:

      sudo -u hbase hbase hbck -metaonly
      

      The checking after which it began to fail is: after this checkin: https://github.com/apache/hbase/commit/818749ff9f261aac4206054d331189e92290b408

      The full output is below. The issue seems the patch does not include -metaOnly

      Testing done:
      I build 0.96 up to commit a6f208d91efff207860b049eb8466a069f0c71a9 and the test passes.

      The output:

      $ hbase org.apache.hadoop.hbase.PerformanceEvaluation --rows=10000 sequentialWrite 1
      $ hbase hbck -metaonly
      ...
