> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
> Affects Versions: 3.0.0
> Environment: Hadoop 3.0.0, HBase 2.0.0 + HBASE-20403.
> (hbase-site.xml) hbase.rs.prefetchblocksonopen=true

> Found the following exception thrown in a HBase RegionServer log (Hadoop
> 3.0.0 + HBase 2.0.0. The hbase prefetch bug HBASE-20403 was fixed on this
> cluster, but I am not sure if that's related at all):

> void sendReadResult(Status statusCode) {
> assert !sentStatusCode : "already sent status code to " + peer;
> try {
> writeReadResult(peer.getOutputStream(), statusCode);
> sentStatusCode = true;
> } catch (IOException e) {
> // It's ok not to be able to send this. But something is probably wrong.
> LOG.info("Could not send read status (" + statusCode + ") to datanode " +
> peer.getRemoteAddressString() + ": " + e.getMessage());
> }
> }
> {code}
> So the NPE was thrown within a exception handler. A possible explanation
> could be that the socket was closed so client couldn't write, and
> Socket#getRemoteSocketAddress() returns null when the socket is closed.
> Suggest check for nullity and return an empty string in
> NioInetPeer.getRemoteAddressString.
