Fang-Yu Rao commented on IMPALA-9180:
-------------------------------------
Thanks [~kwho]!
I am currently working on https://issues.apache.org/jira/browse/IMPALA-9154, a
deadlock that occurs when the Coordinator is propagating an aggregated filter
on a cluster with a very limited number of threads in its thread pool.
One potential solution is to make
[https://github.com/apache/impala/blob/master/be/src/runtime/coordinator.cc#L1094]
an asynchronous call so that the calling thread could be freed and thus there
will be available threads to answer this RPC.
> Remove legacy ImpalaInternalService

> Key: IMPALA-9180
> URL: https://issues.apache.org/jira/browse/IMPALA-9180
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 3.4.0
> Reporter: Michael Ho
> Assignee: Fang-Yu Rao
> Priority: Minor
>
> Now that IMPALA-7984 is done, the legacy Thrift based Impala internal service
> can now be removed. The port 22000 can also be freed up. In addition to code
> change, the doc probably needs to be updated to reflect the fact that 22000
> is no longer in use.
