Subject [jira] Commented: (HADOOP-27) MapRed tries to allocate tasks to nodes that have no available disk space
Date Fri, 30 Jun 2006 16:35:30 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-27?page=comments#action_12418673 ] 

paul sutter commented on HADOOP-27:
-----------------------------------


One impact of this fix is that an invalid directory name in the temp files list will now prevent
a node from running, whereas before that was tolerated.

We have a couple of nodes in our cluster with 3 drives instead of 4 (they each have a dead
drive), and previously we were able to run just fine with one config file on all nodes.
