Key: HDFS-16897
URL: https://issues.apache.org/jira/browse/HDFS-16897
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs
Affects Versions: 3.3.4
Reporter: fanluo
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.
