  <artifactId>bigtable-hbase-2.x-hadoop</artifactId>
  <description>
    Bigtable connector compatible with HBase 2.x. It most of its dependencies
    (hbase &amp; grpc). Its mainly intended to be used by dataflow 2.x to avoid
    version conflicts with grpc &amp; protobuf. Prefer to use
    bigtable-hbase-2.x.
