Tim Armstrong resolved IMPALA-1747.
-----------------------------------
Resolution: Cannot Reproduce
> Improve the response time for Invalidate Metadata
> -------------------------------------------------
>
> Key: IMPALA-1747
> 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_.
