Subject [jira] Commented: (MAPREDUCE-1865) [Rumen] Rumen should also support jobhistory files generated using trunk
Date Wed, 16 Jun 2010 17:52:24 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12879418#action_12879418

Dick King commented on MAPREDUCE-1865:

I have a couple of code review comments on {{mapreduce-1865-v1.2.patch}} .

My small comments are:

1: In {{TestRumenJobTraces.testJobHistoryFilenameProcessing()}}, {{JobID}}'s should probably
be built with the {{JobID(String jtIdentifier, int id)}} constructor.  Also, {{JobID}} jhas
an {{equals(Object)}} method and the raw {{JobID}}'s can therefore be fed into {{assertEquals(String,
Object, Object)}}.

My big comment is: In {{TestRumenJobTraces}} code, can the {{JobHistory}} log files be built
by a minicluster running some trivial job such as a 1 second sleep job, instead of being canned
in {{small-trace-test}} ?
