[jira] [Created] (HBASE-18186) Frequent FileNotFoundExceptions in region server logs

JIRA jira@apache.org
Ashu Pachauri created HBASE-18186:
-------------------------------------

             Summary: Frequent FileNotFoundExceptions in region server logs
                 Key: HBASE-18186
                 URL: https://issues.apache.org/jira/browse/HBASE-18186
             Project: HBase
          Issue Type: Bug
          Components: Compaction, Scanners
    Affects Versions: 1.3.1
            Reporter: Ashu Pachauri


We see frequent FileNotFoundException in regionserver logs on multiple code paths trying to reference non existing store files. I know that there have been multiple bugs in store file accounting of compacted store files. Examples include: HBASE-16964 , HBASE-16754 and HBASE-16788.
Observations:  
1. The issue mentioned here also seems to bear a similar flavor, because we are not seeing rampant dataloss given the frequency of these exceptions in the logs. So, it's more likely an accounting issue, but I could be wrong.
2. The frequency with which this happens on scan heavy workload is at least one order of magnitude higher than a mixed workload.
