Subject LeaseException despite high hbase.regionserver.lease.period
Date Sun, 12 Feb 2012 18:41:35 GMT
Hello,

I'm getting scanner lease exceptions during mapreduce job [1] after running
it for less than 7 minutes. Though I have set
hbase.regionserver.lease.period to 600000 (i.e. 10 min) in hbase
configuration on master and all regionservers and master (and restarted
all). Also set it in job's configuration.

Is there anything else I could do to eliminate the exception?

Thanks,
Alex
