-----------------------------------
Summary: Re-assignment of Partition gets infinitely stuck "Still
in progress" state
Key: KAFKA-9162
URL: https://issues.apache.org/jira/browse/KAFKA-9162
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."
