[jira] [Comment Edited] (CASSANDRA-13010) nodetool compactionstats should say which disk a compaction is writing to

    [ https://issues.apache.org/jira/browse/CASSANDRA-13010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15884908#comment-15884908 ]

Thanks [~jjirsa]!

I've started by adding a targetDirectory to the *CompactionInfo* object. Then I'm working backwards handling new instantiations with appropriate path parameters.

The problem I got at the moment is finding the correct *path* parameter for every such new call.  For instance, in https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/index/internal/CollatedViewIndexBuilder.java#L54; I can't find a proper argument to add as a target directory.

Am I going the right direction? I've tried running the test with building ccm cluster and causing it to run compactions, but the target dir shown for a running compaction is empty, so I probably do something wrong somewhere.

Thanks.
