Subject [jira] [Commented] (HBASE-15264) Implement a fan out HDFS OutputStream
Date Sat, 20 Feb 2016 01:07:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15155254#comment-15155254

Duo Zhang commented on HBASE-15264:

There is no problem if master renamed our WAL directory because we can not start a new WAL
writer any more. This will finally cause the RS abort. And master will only split a log if
it is closed(successfully returned from recoverFileLease) so we will not lose any data. asynchronously
closing WAL writer is also OK I think. I used to miss the rename stage...
