Subject [jira] [Updated] (HBASE-5045) Add the table name and cf name for the next call int the task monitor
Date Sat, 21 Apr 2012 00:19:34 GMT

     [ https://issues.apache.org/jira/browse/HBASE-5045?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Phabricator updated HBASE-5045:
-------------------------------

    Attachment: D2913.1.patch

mbautin requested code review of "[jira] [HBASE-5045] Annotation for Custom Param formatting
and next() RPC call info".
Reviewers: amirshim, Liyin, tedyu, stack, JIRA

  Porting Amir's fix from 89-fb. His original summary below.

  A method for associating pretty print classes with method calls.
  These allow you to get information about a method call given the params it was
  called with and what instance it was called on.

  The first use case is for getting info about a next() RPC call.

TEST PLAN
  Original test plan from Amir: run a script that stresses a regionserver with scan and next()
scans, and check that the information is show in the JSON view of the TaskMonitor

> In the task monitor, we don't have much information about the next call compared to other
operations.
> It would be nice to add the table name and cf name for each next call in the task monitor.
