frequency with which hadoop or hdfs daemons run and refresh information
George Kousiouris 2011-06-10, 11:47

Hi all,

We are having some problems with the refresh rate of the information
coming from hadoop commands. For example, when we decommision a node and
then reinstate it, it seems that it has 0KB capacity attached. If we
stop and start the dfs then it is immediately shown with the correct
capacity.

I guess this is an issue with the frequency some update daemons are
running in the background? And if yes, is there a way to change their
frequency of activation?

BR,
George
