--------------------------------
Summary: Rebalance tool support moving replicas from some specific
tablet servers
Key: KUDU-2914
URL: https://issues.apache.org/jira/browse/KUDU-2914
Project: Kudu
Issue Type: Improvement
Components: CLI
Reporter: YifanZhang
When we need to stop/upgrade some tablet servers in a kudu cluster, these
tservers would become unavailable and tablets on these servers would be
unhealthy in a period of time. In order to ensure the high availability of the
cluster, it's better to move all replicas on these tservers to other tservers
in a cluster, then stop or upgrade tservers. This can be achieved by rebalance
tool to support specifying 'blacklist_tservers'.
