             Summary: Re-assignment of Partition gets infinitely stuck "Still in progress" state
                 Key: KAFKA-9163
                 URL: https://issues.apache.org/jira/browse/KAFKA-9163
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.10.1.1
         Environment: Amazon Linux 1 x86_64 GNU/Linux
            Reporter: vikash kumar


We have 6 node kafka cluster. Out of the 6 machines, 3 of them have both Kafka + zookeeper, and the remaining 3 of them have just kafka.
Recently, we added one more kafka node. While re-assigning the partition to all the nodes (including the newer one), we executed the below command:

/opt/kafka/bin/kafka-reassign-partitions.sh --reassignment-json-file new_assignment_details.json --execute --zookeeper localhost:2181

However, when we verified the status by using the below command,

/opt/kafka/bin/kafka-reassign-partitions.sh --reassignment-json-file new_assignment_details.json --verify --zookeeper localhost:2181

We get the below output. Some of the partitions are re-assignment is still in progress.

/opt/kafka/bin/kafka-reassign-partitions.sh --reassignment-json-file new_assignment_details.json --verify --zookeeper localhost:2181 | grep 'progress'
Reassignment of partition [topic-name,854] is still in progress
Reassignment of partition [topic-name,674] is still in progress
Reassignment of partition [topic-name,944] is still in progress
Reassignment of partition [topic-name,404] is still in progress
Reassignment of partition [topic-name,314] is still in progress
Reassignment of partition [topic-name,853] is still in progress
Reassignment of partition [prom-metrics,403] is still in progress
Reassignment of partition [prom-metrics,134] is still in progress


There is no way to either:

1. Cancel the on-going partition re-assignment.
2. Rollback is also not possible. ( When we try doing that it says that "There is an existing assignment running."
