Vuk Ercegovac resolved IMPALA-4704.
-----------------------------------
Resolution: Fixed
> ImpalaD should not open 21000 and 21050 Ports till Catalog is Received
> ----------------------------------------------------------------------
>
> Key: IMPALA-4704
> URL: https://issues.apache.org/jira/browse/IMPALA-4704
> Project: IMPALA
> Issue Type: Improvement
> Components: Catalog, Frontend
> Affects Versions: Impala 2.5.0
> Reporter: Manish Maheshwari
> Assignee: Vuk Ercegovac
> Labels: impala, ramp-up
>
> Currently ImpalaD's open the frontend connections and this results in query
> failures. The preferred behaviour would be that the ports remain closed till
> the catalog is received and for any reason is the SS connectivity is not
> established after reasonable attempts and timeouts, then the impalad to
> simply shut down.

> com.cloudera.impala.common.AnalysisException: This Impala daemon is not ready
> to accept user requests. Status: Waiting for catalog update from the
> StateStore.

> StateStore.
> {code}
> This will help especially when we have multiple impala'd behind a LB and
> connections can be directed to daemons with the catalog when some
> servers/impala services are been restarted for any reason.
