bigtable-hbase-2.x-hadoop incompatible with hbase-shaded-client 2.x

[xavier-rasschaert-privitar]

The bigtable-hbase-2.x-hadoop dependency expects hbase-shaded-client 2.x, while the code is compiled against HBase 1.x.

Steps to reproduce

1. Setup a Java project and include the dependency com.google.cloud.bigtable:bigtable-hbase-2.x-hadoop:1.15.0. This dependency transitively depends on org.apache.hbase:hbase-shaded-client:2.2.3
2. call getClusterMetrics() on a AbstractBigtableAdmin

Code example

org.apache.hadoop.hbase.client.Connection connection = createConnection();
org.apache.hadoop.hbase.client.AbstractBigtableAdmin admin = connection.getAdmin().
int size = admin.getClusterMetrics().getLiveServerMetrics().size();

Thanks for reporting. I can reproduce the error.

Looks like we will have to pull the implementation of getClusterMetrics() & getClusterStatus out of the shared artifact.

However, please note that the implementation will be hollow: all of the attributes will be empty. Bigtable only provides server metrics via stack driver
