[jira] [Created] (HBASE-17058) Lower epsilon used for jitter verification from HBASE-15324

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

             Summary: Lower epsilon used for jitter verification from HBASE-15324
                 Key: HBASE-17058
                 URL: https://issues.apache.org/jira/browse/HBASE-17058
             Project: HBase
          Issue Type: Bug
          Components: Compaction
    Affects Versions: 1.2.4, 1.1.7, 2.0.0, 1.3.0, 1.4.0
            Reporter: Esteban Gutierrez


The current epsilon used is 1E-6 and its too big it might overflow the desiredMaxFileSize. A trivial fix is to lower the epsilon to 2^-52 or even 2^-53. An option to consider too is just to shift the jitter to always decrement hbase.hregion.max.filesize (MAX_FILESIZE) instead of increase the size of the region and having to deal with the round off.
