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

             Summary: progress in compactionstats is reported wrongly for view builds
                 Key: CASSANDRA-12244
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12244
             Project: Cassandra
          Issue Type: Bug
            Reporter: Tom van der Woerdt
            Priority: Minor


In the view build progress given by compactionstats, there are several issues :

{code}
                                     id   compaction type   keyspace         table   completed       total     unit   progress
   038d3690-4dbe-11e6-b207-21ec388d48e6        View build      mykeyspace   mytable   844 bytes   967 bytes   ranges     87.28%
Active compaction remaining time :        n/a
{code}

1) those are ranges, not bytes
2) it's not at 87.28%, it's at ~4%. the method for calculating progress in Cassandra is wrong: it neglects to sort the tokens it's iterating through (ViewBuilder.java) and thus ends up with a random number.
