> Capture exception in rpcRequestSender.start() in IPC.Connection.run()

> Key: HADOOP-19061
> URL: https://issues.apache.org/jira/browse/HADOOP-19061
> Project: Hadoop Common
> Issue Type: Bug
> Components: ipc
> Affects Versions: 3.5.0
> Reporter: Xing Lin
> Assignee: Xing Lin
> Priority: Major
> Labels: pull-request-available
>
> _rpcRequestThread.start()_ is called outside of the try-catch{} block.
> However, it can throw OOM. In such cases, we fail to start the Connection and
> Connection.rpcRequestThread threads. However, this OOM won't be captured in
> {_}Connection.setupIOStreams(){_}. Instead, that function returns and
> getConnection() will return an Connection object and we will continue with
> _connection.sendRpcRequest(call). sendRpcRequest()_ will then be hanging
> forever at its while loop, because we don't mark this connection as closed
> and we don't have the rpcRequestSender thread to poll the request from the
> queue.
> {code:java}
> IPC.Connection.run()
> @Override
> public void run() {
> // Don't start the ipc parameter sending thread until we start this
> // thread, because the shutdown logic only gets triggered if this
> // thread is started.
> rpcRequestThread.start();
> if (LOG.isDebugEnabled())
> LOG.debug(getName() + ": starting, having connections "
> + connections.size());
> try {
> while (waitForWork()) {//wait here for work - read or close connection
> receiveRpcResponse();
> }
> } catch (Throwable t) {
> // This truly is unexpected, since we catch IOException in
> receiveResponse
> // -- this is only to be really sure that we don't leave a client
> hanging
> // forever.
> LOG.warn("Unexpected error reading responses on connection " + this,
> t);
> markClosed(new IOException("Error reading responses", t));
> }{code}
> while loop in sendRpcRequest
