Subject [jira] [Commented] (HDFS-6156) Simplify the JMX API that provides snapshot information
Date Wed, 26 Mar 2014 09:15:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6156?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13947701#comment-13947701

Shinichi Yamashita commented on HDFS-6156:
------------------------------------------

I think that the following methods are necessary to complete your proposal.

{code}
public SnapshottableDirectory.Bean[] getSnapshottableDirectories();
public Snapshots.Bean[] getSnapshottableDirectories();
{code}

Let me clarify my understanding.

> HDFS-5196 introduces a set of new APIs that provide snapshot information through JMX.
Currently. The API nests {{SnapshotDirectoryMXBean}} into {{SnapshotStatsMXBean}}, creating
another layer of composition.
> This jira proposes to inline {{SnapshotDirectoryMXBean}} into {{SnapshotStatsMXBean}}
and to simplify the API.
