Hello. I'm using Apache Kudu 1.2 on CDH 5.10.
Background --------------- I'm currently using Elasticsearch to serve web analytic service. Elasticsearch is very easy to manage cluster. One nice feature of ES is that I can disable allocation of shard (shard is similar to tablet of Kudu) intentionally so that I can restart one of physical servers without rebalancing shards. Or entire cluster can be rolling restarted. I hope Apache Kudu has similar features. Question ----------- I found that if a tserver doesn't respond for 5 minutes, it starts replicating tablets. And "5 min" can be configured. So far so good. Q1. Can I disable redistributing tablets on failure of a tserver? The reason why I need this is described in Background. Q2. redistribution goes on even if the failed tserver reconnected to cluster. In my test cluster, it took 2 hours to distribute when a tserver which has 3TB data was killed. Q3. `--follower_unavailable_considered_failed_sec` can be changed without restarting cluster? I think this email is somewhat unclear. Please ask me again to clarify if you could not understand me. Thanks, Jason.
