Subject Mapreduce jobtracker recover property
Date Tue, 24 Sep 2013 02:31:31 GMT

I'm using the version Hadoop 1.2.1 in production hdfs, i can see the the
following properties with the value in jobtracker  job.xml,

*mapreduce.job.restart.recover - true*
*mapred.jobtracker.restart.recover - false**

What is the difference and which property will taken by the jobtracker? Do
we need really need these properties?

Also I didn't set the value to those properties in any of the
configurations(eg., mapred-site.xml).

Please help on this.
