[jira] [Created] (HBASE-13200) Improper configuration can leads to
endless lease recovery during failover
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.
