Description

Always see following error log while running:

ERROR datanode.DirectoryScanner (DirectoryScanner.java:<init>(430)) - dfs.datanode.directoryscan.throttle.limit.ms.per.sec set to value below 1 ms/sec. Assuming default value of 1000

<property>
  <name>dfs.datanode.directoryscan.throttle.limit.ms.per.sec</name>
  <value>0</value>
...

The default value should be 1000 and consistent with DFS_DATANODE_DIRECTORYSCAN_THROTTLE_LIMIT_MS_PER_SEC_DEFAULT
