------------------------------------------
Summary: bin/kafka-preferred-replica-election.sh fails if
generated json is bigger than 1MB
Key: KAFKA-8402
URL: https://issues.apache.org/jira/browse/KAFKA-8402
Project: Kafka
Issue Type: Bug
Components: tools
Affects Versions: 1.1.1
Reporter: Vyacheslav Stepanov
If I run script {{bin/kafka-preferred-replica-election.sh}} without specifying
the list of topics/partitions - it will get all topics/partitions from
zookeeper and transform that to json, then it will create zookeeper node at
{{/admin/preferred_replica_election}} using this json as data for that
zookeeper node. If the generated json is bigger than 1MB (default max size of
data of zookeeper node) - the script will fail without giving a good
description of failure. The size of 1MB can be reached if the amount of
topics/partitions is high enough.
