Subject [jira] [Commented] (HBASE-15537) Add multi WAL support for AsyncFSWAL
Date Tue, 05 Apr 2016 13:03:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15226209#comment-15226209

Sean Busbey commented on HBASE-15537:
-------------------------------------

I don't think we need any changes on the HBase side to get the stats that [~stack] wants.
When doing the Cloudera-internal testing for multiwal and HDFS HSM, I gathered these stats
by running HDFS fsck in a loop to get block locations for all files under the WAL directory.
It worked fine, from what I remember.

Unfortunately, I didn't save the logs from that work.
