> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs

> This Jira targets to backport changes in HDFS-14346 and HADOOP-16265 to allow
> better time precision of configuration#getTimeDuration. This is required by
> Standby read, where edit log tailing period needs to be set small.
> Note that HDFS-14346 is only partially backported in this Jira, as it has
> changes based on previous change from HDFS-9847. HDFS-9847 backport is not in
> the scope of this Jira. Therefore, this Jira only targets at backporting the
> minimum change required by Standby read.
