[jira] Created: (HBASE-515) At least double default timeouts
between regionserver and master
At least double default timeouts between regionserver and master
-----------------------------------------------------------------
Key: HBASE-515
URL: https://issues.apache.org/jira/browse/HBASE-515
Project: Hadoop HBase
Issue Type: Improvement
Affects Versions: 0.1.0, 0.2.0, 0.16.0
Reporter: stack
Priority: Blocker
501 added logging of how long we sleep at the end of the HRegionServer main run method before we send heartback back to the master. Last night during upload I saw this:
{code}
2008-03-13 00:03:50,884 WARN org.apache.hadoop.hbase.util.Sleeper: We slept ten times longer than scheduled: 3000
{code}
Above log has since been improved but its saying that we slept > 30 seconds, the default timeout on master/regionserver communications (When the lease expires, master starts giving regions to someone else and when this regionserver reports in, its told to close all its regions).
Server was under load from other processes but still...upload rate was not that rabid.

For something this simple I don't think you need a review. However, I reviewed the patch. +1
