Xiaoyu Yao commented on HDFS-11608:
-----------------------------------
The calculation in my previous comment was incorrect. The actual number of
packet and average packet size are the same with this change.
The second Math.min may not be necessary assuming we have validate the
WritePacketSize is configured properly.

> We've seen HDFS write crashes in the case of huge block size. For example,
> writing a 3G file using 3G block size, HDFS client throws out of memory
> exception. DataNode gives out IOException. After changing heap size limit,
> DFSOutputStream ResponseProcessor exception is seen followed by Broken pipe
> and pipeline recovery.
> Give below:
> DN exception,
