Subject [jira] [Created] (CASSANDRA-7605) compactionstats reports incorrect byte values
Date Thu, 24 Jul 2014 05:56:39 GMT
Peter Haggerty created CASSANDRA-7605:
-----------------------------------------

             Summary: compactionstats reports incorrect byte values
                 Key: CASSANDRA-7605
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7605
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: 2.0.9, Java 1.7.0_55
            Reporter: Peter Haggerty


The output of nodetool compactionstats (while a compaction is running) is incorrect.

The output from nodetool compactionhistory and the log both match and they disagree with the
output from compactionstats.

What nodetool said during the compaction was almost certainly wrong given the sizes of files
on disk:
   completed           total      unit  progress
144713163589    146631071165     bytes    98.69%

nodetool compactionhistory and the log both report the same values for that compaction:
52,596,321,269 bytes to 38,575,881,134

The compactionhistory/log values make much more sense given the size of the files on disk.
