Yi Liu commented on HDFS-7698:
------------------------------
Thanks Colin for the patch.
It looks good to me, just few comments. +1 after addressing.
# In DFSInputStream#tryReadZeroCopy, we should also hold the {{infoLock}} for
{{readStatistics}}.
# For HdfsDataInputStream#getAllBlocks, we could remove the {{synchronized}}
too.
> Fix locking on HDFS read statistics and add a method for clearing them.
