Subject [jira] [Commented] (HDFS-12395) Support erasure coding policy operations in namenode edit log
Date Mon, 11 Sep 2017 11:21:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12395?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16161095#comment-16161095

Rakesh R commented on HDFS-12395:

Thanks [~Sammi] for the continuous efforts.

bq.  I'm not very sure about the "Update javadocs" comments, is that because new parameter
"logRetryCache" is added for involved API?
Yes, good to could update javadoc,
(1) with new param. 
   * @param logRetryCache whether to record RPC ids in editlog for retry cache
   *                      rebuilding
(2) Secondly, since you are touching {{FSDirErasureCodingOp}} functions, could you please
add javadoc for the APIs which doesn't have details presently.
FSDirErasureCodingOp#addErasureCodingPolicy, FSDirErasureCodingOp#removeErasureCodingPolicy,
FSDirErasureCodingOp#enableErasureCodingPolicy, FSDirErasureCodingOp#disableErasureCodingPolicy
