> h2. Setup Clusters
>  * Setup Local Flink Cluster: [https://ci.apache.org/projects/flink/flink-docs-release-1.8/tutorials/local_setup.html]
>  * Setup Kubernetes Flink Cluster using Minikube: [https://ci.apache.org/projects/flink/flink-docs-release-1.8/ops/deployment/kubernetes.html]
> h2. Verify Clusters
> Execute command “./bin/flink run examples/streaming/WordCount.jar”. Both Local and K8S Flink Cluster work fine.
> h2. Using Apache Beam Flink Runner
> Instruction: [https://beam.apache.org/documentation/runners/flink/]
> Sample Pipeline Code:
> {code:java}
> import apache_beam as beam 
> from apache_beam.options.pipeline_options import PipelineOptions
> options = PipelineOptions([
>     "--runner=PortableRunner",
>     "--job_endpoint=localhost:8099",
>     "--environment_type=LOOPBACK"
> ])
> with beam.Pipeline(options=options) as pipeline:
>     data = ["Sample data",
>             "Sample data - 0",
>             "Sample data - 1"]
>     raw_data = (pipeline
>             | 'CreateHardCodeData' >> beam.Create(data)
>             | 'Map' >> beam.Map(lambda line : line + '.')
>             | 'Print' >> beam.Map(print)){code}
> Verify different environment_type in Python SDK Harness Configuration
>  *environment_type=LOOPBACK*
>  # Run pipeline on local cluster: Works Fine
>  # Run pipeline on K8S cluster, Exceptions are thrown:
>  java.lang.Exception: The user defined 'open()' method caused an exception: org.apache.beam.vendor.grpc.v1p21p0.io.grpc.StatusRuntimeException: UNAVAILABLE: io exception Caused by: org.apache.beam.vendor.grpc.v1p21p0.io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: localhost/127.0.0.1:51017
