Subject [jira] Commented: (MAPREDUCE-777) A method for finding and tracking jobs from the new API
Date Thu, 17 Sep 2009 11:11:58 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-777?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12756478#action_12756478
] 

Tom White commented on MAPREDUCE-777:
-------------------------------------

More comments, mainly naming:

* There are occurrences of both "blacklist" and "blackList" in the public API (e.g. TaskTrackerInfo#getReasonForBlackList()
and getBlacklistReport()). Either is correct since the word may be spelled as "blacklist"
or "black list", but we need to be consistent throughout. 
* Cluster#getFs() would be better as getFileSystem() (particularly with the debate in HADOOP-6223).
Also it would be good to have javadoc describing the fact it is returning the file system
where job-specific files are placed.
* JobStatus#{setup,map,reduce,cleanup}Progress() would be better as getters to be consistent
with the rest of the class.
* TaskCompletionEvent#getTaskAttemptID() should be getTaskAttemptId() to be consistent with
getEventId().
* TaskCompletionEvent#setTaskID() should be setTaskAttemptId().
* TaskReport's method names should be made consistent with this convention too.

> We need to create a replacement interface for the JobClient API in the new interface.
In particular, the user needs to be able to query and track jobs that were launched by other
processes.
