Review comment:
Thanks @tomscut for the comment and review.
The detailed log here is this:
`
2022-01-18 16:37:56,653 DEBUG org.apache.hadoop.ipc.Server: Call#75 Retry#0
org.apache.hadoop.hdfs.protocol.ClientProtocol.getFileInfo from
xxxx.xxxx.xxxx.xxxx:port has entered the CallQueue and is waiting to be
processed.
2022-01-18 16:37:56,654 DEBUG org.apache.hadoop.ipc.Server: Call#76 Retry#0
org.apache.hadoop.hdfs.protocol.ClientProtocol.getFileInfo from
xxxx.xxxx.xxxx.xxxx:port has entered the CallQueue and is waiting to be
processed.
`
When the Call is processed by Hanler, the detailed log is as follows:
`
2022-01-18 16:37:59,725 [5178363759] - WARN [IPC Server handler 126 on
8025:Server@494] - Slow RPC : create took 509 milliseconds to process from
client Call#76 Retry#0
org.apache.hadoop.hdfs.protocol.ClientProtocol.getFileInfo from
xxxx.xxxx.xxxx.xxxx:port
`
In my opinion, the Calls recorded in these two places should be consistent.
@tomscut , do you have any good suggestions.
