Kai Zheng commented on HDFS-12393:
----------------------------------
Thanks [~legend] for the ping.
Why {{Shorts.BYTES}} would make it accurate? Could you explain some bit?
{code}
- int totalLen = payloadLen + headerLen;
+ int totalLen = payloadLen + headerLen + Shorts.BYTES;
{code}
I noticed the following codes, not sure if you aware of it.
{code}
// Make sure we have space for the whole packet, and
// read it.
reallocPacketBuf(PacketHeader.PKT_LENGTHS_LEN +
dataPlusChecksumLen + headerLen);
...
public static final int PKT_LENGTHS_LEN =
Ints.BYTES + Shorts.BYTES;
{code}

> So {{totalLen = payloadLen + headerLen + length(HLEN)}}
