> When running a Beam pipeline using Flink as backend, the python sdk harness
> hangs when trying to install pip packages. Tested using Flink 1.10.3.
> Images used:
> apache/beam_python3.7_sdk:2.28.0
> apache/flink:1.10.3
> Beam args used are:
> "--runner=FlinkRunner",
> "–flink_version=1.10", //same with 1.13

> "--flink_master=[http://flink-jobmanager.default:8081|http://flink-jobmanager.default:8081/]";,
> f"--artifacts_dir=/mnt/flink",
> "--environment_type=EXTERNAL",
> "--environment_config=localhost:50000",

> Specifically this was tested by running a TFX pipeline which gets submitted
> and registered as it should, but the SDK Harness hangs when installing:
