[GitHub] [pinot] 61yao opened a new issue, #9720: [multistage] [error-handling] MailboxContentStreamObserver poll infinite loop
61yao opened a new issue, #9720:
URL: https://github.com/apache/pinot/issues/9720
Here is how it happens:
Mailbox.MailboxContent content = _receivingBuffer.poll(DEFAULT_MAILBOX_POLL_TIMEOUT, TimeUnit.MILLISECONDS);
Say we never receive this mailbox due to network or the issue stated in sort operator.
_receivingBuffer.pool will throw an exception and log an error.
however _isCompleted is not set to true. The code will start while loop again.
This receive is a blocking call. So we don't have timeout to break this.

_receivingBuffer.poll try catch only catches InterruptedException and all rest of the exception bubbles up.
in this case InterruptedException means some manual interrupt (e.g. query cancellation). so i don't think this would stuck in an infinite loop.
also this is not a blocking call. poll is a park-wait this should be related to #9615
