Zhe Zhang commented on HDFS-8328:
---------------------------------
bq. paddingBufferToLen(..) for multiple zeroStripeBuffers[] is wasting time.
One zeroStripeBuffer is enough.
Good thought Walter. But as Kai mentioned on another JIRA, the input buffers
could be altered in the decode method. Maybe we should do this zero copy update
after the HADOOP side changes to keep input buffers unchanged.
> Follow-on to update decode for DataNode striped blocks reconstruction
