Subject [jira] [Created] (HBASE-13200) Improper configuration can leads to endless lease recovery during failover
Date Wed, 11 Mar 2015 12:01:38 GMT
He Liangliang created HBASE-13200:
-------------------------------------

             Summary: Improper configuration can leads to endless lease recovery during failover
                 Key: HBASE-13200
                 URL: https://issues.apache.org/jira/browse/HBASE-13200
             Project: HBase
          Issue Type: Bug
          Components: MTTR
            Reporter: He Liangliang
            Assignee: He Liangliang


When a node (DN+RS) has machine/OS level failure, another RS will try to do lease recovery
for the log file. It will retry for every hbase.lease.recovery.dfs.timeout (default to 61s)
from the second time. When the hdfs configuration is not properly configured (e.g. socket
connection timeout) and without patch HDFS-4721, the lease recovery time can exceeded the
timeout specified by hbase.lease.recovery.dfs.timeout. This will lead to  endless retries
and preemptions until the final timeout.
