Subject [jira] Commented: (HBASE-581) Allow adding filters to TableInputFormat (At same time, ensure TIF and TOF are subclassable)
Date Wed, 23 Apr 2008 16:19:21 GMT

    [ https://issues.apache.org/jira/browse/HBASE-581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12591671#action_12591671
] 

David Alves commented on HBASE-581:
-----------------------------------

On another subject getSplits always returns the same number independent of "mapred.map.tasks".
Which means applications will always have the same number of maps as of splits which can overload
hbase (in my experience 10 maps that use TIF on just two nodes completely overload Hbase,
meaning not only that the M/R job will fail but also that regionservers go down). 
So getSplits() should take "mapred.map.tasks" into account right?
