Subject any way to set hadoop daemons periodicity?
Date Thu, 20 Sep 2012 14:39:58 GMT

Hi all,

I have noticed that sometimes the hdfs takes too long to act upon a 
specific change in the configuration e.g. the replication factor. While 
the under/over replicated state of a file is immediately detected, the 
corrective action may take some time, even if the file sizes are very 
small and the cluster is idle.

Is there any way to make this process somehow predictable?E.g. through 
some configuration setting regarding the time intervals of the daemons?
