lei w updated HDFS-16003:
-------------------------
Description: In BlockManager#processReport( ) method, we will print
invalidated blocks if log level is debug。We always traverse this
invalidatedBlocks list without considering the log level。I suggest to give
priority to the log level before printing, which can save the time of traversal
if log level is info. (was: In BlockManager#processReport( ) method, we will
print )
> ProcessReport print invalidatedBlocks should judge debug level at first
