Leo Xuzhang Lin commented on KAFKA-3033:
----------------------------------------
Updates. After restarting the cluster, the topic 'test' was stuck in infinite
leader election which causes the server to run out of file descriptors.
> Reassigning partition stuck in progress

> Key: KAFKA-3033
> URL: https://issues.apache.org/jira/browse/KAFKA-3033
> Project: Kafka
> Issue Type: Bug
> Components: replication
> Affects Versions: 0.9.0.0
> Environment: centos 7.2
> Reporter: Leo Xuzhang Lin
> Assignee: Neha Narkhede
> Priority: Critical
>
> We were trying to increase the replication factor on a test topic we've
> created.
> We followed the documentation's instruction:
> http://kafka.apache.org/documentation.html#basic_ops_increase_replication_factor
> and received:
> ```
> Current partition replica assignment
> {"version":1,"partitions":[{"topic":"test","partition":0,"replicas":[1]}]}
> Save this to use as the --reassignment-json-file option during rollback
> Successfully started reassignment of partitions
> {"version":1,"partitions":[{"topic":"test"
> ,"partition":0,"replicas":["1","2","3"]}]}
> ```
> After that whenever we try verify, it is stuck on:
> ```
> Status of partition reassignment:
> Reassignment of partition [test,0] is still in progress
> ```
> - We tried restarting the cluster and it still did not work.
> - The topic has 1 partition
> - The zookeeper /admin/reassign_partitions znode is empty
