Mehran Hassani commented on HDFS-9618:
--------------------------------------
Correct me if I am wrong but I think self4j checks for all the log levels
before making the string so doing IsLevelEnabled() is unnecessary when you use
it.
> Fix mismatch between log level and guard in
> BlockManager#computeRecoveryWorkForBlocks
