Re: Are job statistic logs right in the 0.23 version of Hadoop?

[Mahadev Konar <ma...@hortonworks.com>]

Moving it to mapreduce-list.
Sophie,

This could just be a bug a 0.23. 0.23 does not have
jobtrackers/tasktrackers.

 Could you see if you can recreate this? If yes, please do file a jira on
this.

thanks
mahadev
