Arpit Agarwal commented on HDFS-6860:
-------------------------------------
Thanks Chang.
# In {{logAddStoredBlock}}, we can just fix the call to {{if
(!blockLog.isInfoEnabled())}} at the start of the function. Then we skip the
unnecessary StringBuilder logic.
# Looks like patch needs to be rebased to current trunk.
+1 with these fixed.
