Dead Node and Under Replication
Hi Guys,
How do I tell hadoop to wait longer before fixing Under-Replication when
a node dies. Currently I have a node down which crashed, and hadoop
detected it down and is busy fixing Under-Replication. The problem is
that the extra load required to fix replication is causing our
application not to function correctly. I want to somehow tell hadoop to
stop fixing the Under-Replication until a non-peak time.
Is there like a timeout or a threshold setting I can set to tell hadoop
not to fix replication immediately, but rather to wait for a period of
time? Anything will be better than doing it during a peak time.
Hadoop Version: 1.0.1
dfs.replication = 2
datanodes = 3
Regards,
Seraph
