-------------------------------------
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.
