Subject [jira] [Updated] (HDFS-2306) NameNode web UI should show information about recent checkpoints
Date Mon, 12 Sep 2011 23:39:09 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2306?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aaron T. Myers updated HDFS-2306:
---------------------------------

    Attachment: hdfs-2306.1.patch

Updated patch which addresses Todd's comments.

bq. If we can redo the checkpoint upload so it doesn't have a separate requester address and
callback address, that will be easier to follow and simplify the table as above.

Agreed, but it seems like that could reasonably be done as a separate JIRA. Is that OK by
you, Todd?

> It would be nice if the NN web UI showed the 2NN address, timestamp, number of edits,
etc. of the last few checkpoints.
