>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: hdfs
>    Affects Versions: 3.3.4
>            Reporter: fanluo
>            Priority: Minor
>              Labels: pull-request-available
>
> 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.
