Hi folks,
We have recently got a strange issue with kafka consumer.
Consumer thread was hanging infinitely.
Can someone advise how to approach this?
kafka version is 1.0.2.
we have found following error at broker side.
[2020-01-14 12:17:54,454] DEBUG [GroupMetadataManager brokerId=1002] Offset

here is also tread dump on consumer side
