Subject [jira] Commented: (HADOOP-5388) Add ids to tables in JSP pages to ease scraping of the data.
Date Wed, 04 Mar 2009 11:33:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5388?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678703#action_12678703

Sreekanth Ramakrishnan commented on HADOOP-5388:

I am trying to monitor the task failures. Suppose if we want a script which is run periodically
on a cluster which looks at the running jobs in the cluster and then check for task failures
in the same and outputs the jobid|attemptid|failure reason.

In this case, currently I would have to hard code per page level.

True, in long run we should be doing this REST/XML way but as a stop gap measure we should
be doing something so that these can be done. We should proably expose services from JobTracker
which provides JSON/XML data to different clients which can make used of those information.
But then I think arriving there would take quite a bit of time.

> Currently, the tables which are generated by the JSP pages are lacking id's. If the tables
had id then it would ease the pain of writing scrapping utilities.
