Beam JIRA Bot updated BEAM-12244:
---------------------------------
Labels: (was: stale-P2)
> Failure to connect to expansion service with GRPC local secure channel
> ----------------------------------------------------------------------

> Key: BEAM-12244
> URL: https://issues.apache.org/jira/browse/BEAM-12244
> Project: Beam
> Issue Type: Bug
> Components: cross-language, io-py-kafka
> Reporter: Nir Gazit
> Priority: P3
> Time Spent: 5h
> Remaining Estimate: 0h

> There seem to be a discrepancy between how Beam Python SDK connects to the
> job endpoint and the artifact endpoint (where it always uses insecure GRPC
> connection), and the expansion service (where it [tries to
> use|https://github.com/apache/beam/blob/master/sdks/python/apache_beam/transforms/external.py#L322]
> local secure channel if available in the GRPC module).
> This has caused an error to be thrown when trying to connect to a remote
> Flink cluster:
> {code:none}
