Subject Re: block replication
Date Sat, 28 Dec 2013 03:10:49 GMT
well i couldn't find any property in
http://hadoop.apache.org/docs/r1.2.1/hdfs-default.html that sets the time
interval time consider a node as dead.

I saw there is a property dfs.namenode.heartbeat.recheck-interval or
heartbeat.recheck.interval, but i couldn't find it there. is it removed?
or am i looking at wrong place?
