A 3 node kafka broker cluster went down yesterday (all nodes) and I just noticed it this morning. When I restarted it this morning, I see a lengthy list of messages like this:
Loading log 'mytopic-partitionNum" Recovering unflushed segment 'some number' of in log mytopic-partitionNum. Completed load of log mytopic-partitionNum with log end offset someOffset It's been going on for more than 30 minutes since I restarted the broker. I have quite a few partitions (over 1000) but I still wouldn't expect it to take such a long time. Any ideas on how I should investigate the problem? Thanks!
