Connection refused exception
Hello,
I’m wondering if anyone has seen a similar stack trace before as there isn’t a lot of info provided. I’m wondering if the connection refused is from one operator to another or the kafkaInputOperator being unable to connect to kafka.
Any ideas? Here’s the stacktrace:

Is the exception reproducible? If yes, can you provide full app master
log with the debug level enabled.
Thank you,
Vlad

Re: Connection refused exception
Posted by "Feldkamp, Brandon (CONT)" <Br...@capitalone.com>.
Unfortunately, we’re only seeing the initial connection refused exception that I posted. So, if the issue is related to the buffer server as suggested below, is that something we can mitigate? Do we need to allocate more memory to the buffer servers?

Can you check in stram events on the gateway UI, you can select a time range to begin at the start of the application so you can see the series of events that happened in a timeline. Then you will find the first error in that list. You can find stram events in the logical tab to the right for the application in monitor page.

Ashwin.

Subject: Re: Connection refused exception
Brandon,
Is the stacktrace from the app master log or is it from a local mode run? The exception is raised due to the buffer server termination in one of the operators containers and I guess that it happens when app master tries to purge data from the buffer server. Check the operators containers logs for exceptions/errors unless the application was started in the local mode. In the later case, try to enable DEBUG level.
Thank you,
Vlad

Re: Connection refused exception
Posted by Ashwin Chandra Putta <as...@gmail.com>.
Can you check in stram events on the gateway UI, you can select a time
range to begin at the start of the application so you can see the series of
events that happened in a timeline. Then you will find the first error in
that list. You can find stram events in the logical tab to the right for
the application in monitor page.
Regards,
Ashwin.

Re: Connection refused exception
Posted by Vlad Rozov <v....@datatorrent.com>.
Hmm, that is strange. I would expect an ERROR in the KafkaInputOperator
around 21:01. Please check the earliest killed container log.
2016-11-24 21:01:01,839 [IPC Server handler 4 on 44453] ERROR
stram.StreamingContainerManager processOperatorFailure - Initiating
container restart after operator failure

Subject: Re: Connection refused exception
Brandon,
Is the stacktrace from the app master log or is it from a local mode run? The exception is raised due to the buffer server termination in one of the operators containers and I guess that it happens when app master tries to purge data from the buffer server. Check the operators containers logs for exceptions/errors unless the application was started in the local mode. In the later case, try to enable DEBUG level.
Thank you,

Hello,
I’m wondering if anyone has seen a similar stack trace before as there isn’t a lot of info provided. I’m wondering if the connection refused is from one operator to another or the kafkaInputOperator being unable to connect to kafka.
Any ideas? Here’s the stacktrace:

Re: Connection refused exception

There was a bug in the 3.5 release, this could be it. We fixed it and put
it into 3.5.1-snapshot. The detail are in JIRA, I don't have access to it
right now.

I would let some of the kafka experts in the group take a look at this and
suggest further action. If they don't respond I can investigate this
exception further.
Thanks.

This is not related to kafkaInputOperator talking to Kafka. Do you see any other exceptions in the logs around this exception before or after?
