> Recommission a datanode with 500k blocks may pause NN for 30 seconds

> Project: Hadoop HDFS

>
> In BlockManager, processOverReplicatedBlocksOnReCommission is called within
> the namespace lock. There is a (not very useful) log message printed in
> processOverReplicatedBlock. When there is a large number of blocks stored in
> a storage, printing the log message for each block can pause NN to process
> any other operations. We did see that it could pause NN for 30 seconds for
> a storage with 500k blocks.
> I suggest to change the log message to trace level as a quick fix.
