             Summary: Support to submit Jobs using HBaseIO to DataflowRunner without local access to HBase Cluster
                 Key: BEAM-13141
                 URL: https://issues.apache.org/jira/browse/BEAM-13141
             Project: Beam
          Issue Type: Improvement
          Components: sdk-java-core
            Reporter: Prathap Kumar Parvathareddy


+*Context*+

As of today HBase IO interacts with Hbase cluster while building execution graph for validating the existence of table, calculating splits etc 

https://github.com/apache/beam/blob/master/sdks/java/io/hbase/src/main/java/org/apache/beam/sdk/io/hbase/HBaseIO.java#L237

In certain scenarios dataflow jobs are launched from systems that does not have network access to Hbase cluster during graph construction stage. but can access only during execution time on google cloud. However due to current implementation of local access to HbaseIO, the job can be launched only from systems that has network access to Hbase Cluster.

*+Requirement+*

 Modify HbaseIO to accept a flag (say hasLocalAccess) and if flag is set to false defer validations , split calculation logic etc to job execution time rather than job construction time.
