Arpit Agarwal commented on HDFS-9262:
-------------------------------------
Thanks [~xiaobingo]. My comments:
# Similar as the other jiras, FsDatasetImpl need not extend ReconfigurableBase.
We don't need FsDatasetImpl#getNewConf and #getReconfigurableProperties. You
can also replace reconfigurePropertyImpl with updateLazyWriterInterval.
# Unintentional indenting lines 138-146?
+1 otherwise.
> Reconfigure DN lazy writer interval on the fly
