> The Thrift ClientCache does not have a size limit
> -------------------------------------------------
>
> Key: IMPALA-3609
> URL: https://issues.apache.org/jira/browse/IMPALA-3609
> Project: IMPALA
> Issue Type: Bug
> Components: Distributed Exec
> Affects Versions: Impala 2.6.0
> Reporter: Tim Armstrong
> Priority: Major
> Labels: resource-management
>
> Our Thrift ClientCache's can grow to unbounded size without evicting entries.
> We should bound the size to a reasonable level and potentially just evict
> connections after they reach a certain age.
> We've increased thrift buffer sizes in recent releases, so it's becoming more
> important to free up memory from unused connections. See IMPALA-3599.
