Eli Collins reassigned HDFS-4197:
---------------------------------
Assignee: Daisuke Kobayashi
> SNN JMX is lacking checkpoint info
> ----------------------------------
>
> Key: HDFS-4197
> URL: https://issues.apache.org/jira/browse/HDFS-4197
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: name-node
> Affects Versions: 2.0.2-alpha
> Reporter: Andy Isaacson
> Assignee: Daisuke Kobayashi
> Labels: newbie
>
> The SecondaryNameNode status.jsp page contains the following:
> {noformat}
> SecondaryNameNode Status
> Name Node Address : snn1/172.29.122.91:50020
> Start Time : Fri Nov 09 09:25:29 PST 2012
> Last Checkpoint Time : Thu Nov 15 15:35:06 PST 2012
> Checkpoint Period : 30 seconds
> Checkpoint Size : 39.06 KB (= 40000 bytes)
> Checkpoint Dirs : [file:///tmp/hdfs-adi/dfs/namesecondary]
> Checkpoint Edits Dirs: [file:///tmp/hdfs-adi/dfs/namesecondary]
> {noformat}
> The JMX page at {{:50090/jmx}} should also provide this info; at the very
> least the Last Checkpoint Time and Checkpoint Size so that users are not
> tempted to scrape the {{status.jsp}} output. Perhaps I'm missing it but
> these data seem to be missing.
