[jira] [Updated] (CASSANDRA-12244) progress in compactionstats is
reported wrongly for view builds
[ https://issues.apache.org/jira/browse/CASSANDRA-12244?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Shuler updated CASSANDRA-12244:
---------------------------------------

> 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
> Assignee: ZhaoYang
> Priority: Minor
> Labels: lhf
> Fix For: 3.0.x

> 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.
