Subject [jira] [Commented] (HDFS-8323) Bump GenerationStamp for write faliure in DFSStripedOutputStream
Date Wed, 13 May 2015 18:59:01 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8323?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14542451#comment-14542451

Jing Zhao commented on HDFS-8323:

Thanks for working on this, Nicholas! The patch looks good to me. Some comments but most of
them can be done in separate jiras as follow-on work:
# Currently when bumping the GS we close all existing streamers which is expensive. It will
be nice we can reuse these connections. This may be a big change thus we can do it in separate
# We can also do some code refactoring (in trunk maybe) to separate {{setupPipelineForAppendOrRecovery}}
into multiple functions for handling different failure scenarios.

+1 for the current patch.
