Subject [jira] [Resolved] (HADOOP-3436) Useless synchronized in JobTracker
Date Wed, 15 Jun 2011 17:13:47 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-3436?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Harsh J resolved HADOOP-3436.
-----------------------------

    Resolution: Not A Problem

Does not appear to be a problem w.r.t. trunk. There is no such variable held (a collection
is used instead, and that requires to hold JT lock and is synchronized (per comments)).

Resolving as "Not a problem" (anymore). Stale issue.

> In the original code, numTaskTrackers is fetch in a synchronized way, which is useless
because anyway it might be change during the running of the algorithm.
