[astubbs]

What version?

[jatindersthind]

What version?

0.5.2.1

@astubbs Also we see multiple different types of errors due to which parallelconsumer shutdown happens, but our java process still keeps running. Is there any way through which we can shutdown out process, maybe we can get event from some kind of shutdown listener on parallelConsumer?

[astubbs]

Yes, you can periodically call the isClosedOrFailed method.

A shutdown listener is an interesting suggestion - feel free to create a feature request. There isn't anything like that atm.

Please update to the latest version, then try again?

[jatindersthind]

Please update to the latest version, then try again?

Sure will try to update to 0.5.2.3 Also will try working on isClosedOrFailed periodic checks

[astubbs]

We're also about to release a metrics package which might be relevant - so stay tuned on:

• #27

Yes, you can periodically call the isClosedOrFailed method.

Just need to confirm one thing is this method only available in ParallelEoSStreamProcessor(AbstractParallelEoSStreamProcessor) and not at interface level ParallelConsumer or ParallelStreamProcessor? If yes then we will have to cast it to ParallelEoSStreamProcessor

[astubbs]

Ah yea - will have to fix that

[astubbs]

An you include earlier logs? The errors you showed were the errors from trying to shutdown when the client was already closed. I can add some checks to avoid those.
