Subject Kafka Streams stopped with errors, failed to reinitialize itself
Date Wed, 03 May 2017 11:57:14 GMT
Hi,



I want to report an issue where in addition of a server at runtime in my
streams compute cluster caused errors and subsequent complete halting of
the cluster. I am not sure if this is the actual issue, but this was
something I did differently while 18 hour smooth run of the streams app.



Initially, I had one machine working on my Kafka topic, which contains
impressions and clicks. The job was running overnight, in the morning I
just added another machine to the cluster and this is when every time stuck
after working fine for some time.



Please find the kafka_log_snippet and poc_log_snippet attached.



Thereafter, failing of these nodes, I tried to restart just one machine on
my compute cluster to see if it can initialize itself.

Please the logs attached for the same as well. Following were the logs I
saw quite often.
