>                 URL: https://issues.apache.org/jira/browse/IMPALA-1747
>             Project: IMPALA
>          Issue Type: Improvement
>          Components: Catalog
>    Affects Versions: Impala 2.0.1
>            Reporter: Alan Choi
>            Priority: Major
>              Labels: catalog-server, performance, usability
>
> When multiple "invalidate metadata" is executed (either concurrently, or sequentially), the response time (other than the first call) is longer than a few seconds. This doesn't match the expectation that "invalidate metadata" should return almost immediately.
> One possible cause is that there's contention on the catalogLock_.
