Hi, After switching from the Kafka version 2.10-0.8.1.1 to 2.10-0.8.2.1 I frequently encounter the exception below, which result in re-election of the leaders for the partitions. This exception occurs every one ~ several hours.
We have a 3-node-cluster. We didn't see this problem when we still use the version 0.8.1.1. It seems neither to be a problem of limits in open sockets/files - as increasing the limits didn't alleviate the problem. Does anyone have similar problem? What are the possible fix? I noticed that a similar issue was reported in (http://mail-archives.apache.org/mod_mbox/kafka-users/201501.mbox/%3ccahwhrrw7qmlbyv85pe7vg17ksfrmswtwhxgsjuhjawdfewb...@mail.gmail.com%3E) for version 0.8.1. Did you find a solution at the end? Thanks!
