[jira] [Commented] (CASSANDRA-18055) Nodetool Compact set the compaction type incorrectly
[ https://issues.apache.org/jira/browse/CASSANDRA-18055?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17635348#comment-17635348 ]
maxwellguo commented on CASSANDRA-18055:
----------------------------------------
I just add one ut for this patch , the ut just perform a major without range /dk specified. and I found it not easy to add test for this because when perform a major at one time and the compactionstast at another time ,the compaction task may just finished before the compactionstast command finished its's execution.
[~brandon.williams][~stefan.miklosovic] can you give some advice on this patch ? or just help to have a look on this

> When using nodetool compactionstats to see what does the c*'s compactions are doing ,the output has got a column named "compaction type", but It seem that major compaction and minor compaction 's type are all name Compaction, after read the code I found that may be the the MAJOR_COMPACTION OperationType is not setted into AbstractCompactionTask
> at this method : CompactionStrategyManager -> getMaximalTasks .When we peform a major compact without any arguments we will got this execute path :
> {code:java}
> // Some comments here
> Compact.java : probe.forceKeyspaceCompaction(splitOutput, keyspace, tableNames);
> --->
> ColumnFamilyStore.java : cfStore.forceMajorCompaction(splitOutput);
> --->
> CompactionManager.java : submitMaximal(cfStore, gcBefore, splitOutput, OperationType.MAJOR_COMPACTION);
> {code}
> Unfortunately OperationType.MAJOR_COMPACTION is not rightly setted.
> see the picture on the right I perform a major compact , and on the left the compactionstats show the type is only Compaction ;
> I think it is import for us to know wether the task is a major or a minor .
