--------------------------------------
Summary: 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
