[jira] [Created] (SOLR-12850) SOLR Unaware When Index Has Corrupt Checksum

JIRA jira@apache.org
Stephen Lewis Bianamara created SOLR-12850:

             Summary: SOLR Unaware When Index Has Corrupt Checksum
                 Key: SOLR-12850
                 URL: https://issues.apache.org/jira/browse/SOLR-12850
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
    Affects Versions: 6.6.2
            Reporter: Stephen Lewis Bianamara

If a SOLR node gets a corrupted checksum in its index, it will still report as "healthy" but all writes routing to that node will fail. Thus leading to a total write outage  which is totally silent server side.


I think this behavior should report within the cluster status. I think "Down" is appropriate, and then that should lead to a recovery triggering. Perhaps though a new category of "CorruptIndex" or something is more appropriate. However it happens, I believe the right response is (a) release leader lock if held (b) once new leader is elected, copy that leader's index
