> Key: IMPALA-1760
> URL: https://issues.apache.org/jira/browse/IMPALA-1760
> Project: IMPALA
> Issue Type: New Feature
> Components: Distributed Exec
> Affects Versions: Impala 2.1.1
> Reporter: Henry Robinson
> Assignee: Tim Armstrong
> Priority: Critical
> Labels: resource-management, scalability, scheduler, usability
>
> In larger clusters, node maintenance is a frequent occurrence. There's no way
> currently to stop an Impala node without failing running queries, without
> draining queries across the whole cluster first. We should fix that.
