> HDFS-13639 improves the performance of short-circuit shm slot releasing by
> reusing the domain socket that the client previously used to send release
> request to the DataNode.
> This is good when there are only one DataNode locates with the client (truth
> in most of the production environment). However, if we launch multiple
> DataNodes on a machine (usually for testing, e.g. Impala's end-to-end tests),
> the request could be sent to the wrong DataNode. See an example in
> IMPALA-11234.
