Xiaoqiao He commented on HDFS-16003:
------------------------------------
Thanks [~lei w] for your proposal. It makes sense to me. But I am concerned if
it will loss some trace information about some specific block.
> ProcessReport print invalidatedBlocks should judge debug level at first

> 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.
