Description

in our production cluster env , we found some exception in datanode logs，its frequently print below error
in ~~HDFS-2054~~ we only ignored message starting with `Broken pipe` which may not enough for the following case:

this situation look like related to short-circuit read. in ~~HDFS-4354~~ the error has been wrapped, so that our previous judgment conditions are invalid.

maybe we can improve it.
