---------------------------------
Summary: Add a configuration option to enable in-progress edit log
tailing
Key: HDFS-10519
URL: https://issues.apache.org/jira/browse/HDFS-10519
Project: Hadoop HDFS
Issue Type: Improvement
Components: ha
Reporter: Jiayi Zhou
Assignee: Jiayi Zhou
Priority: Minor
Standby Namenode has the option to do in-progress edit log tailing to improve
the data freshness. In-progress tailing is already implemented, but it's not
enabled as default configuration. And there's no related configuration key to
turn it on.
Adding a related configuration key to let Standby Namenode is reasonable and
would be a basis for further improvement on Standby Namenode.
