Is your HMaster running? Can you please check HMaster logs? Are you passing hbase-site.xml to your HBase conf (not clear from the code you shared)?

1. Please check, that the /etc/hbase/conf is in the classpath or set HBASE_CONF_DIR env to this path (I expect that you are running it on the node where hbase client is deployed, otherwise copy it from your cluster to the node where client is running).

2. Before running a custom application make sure that you are able to access HBase using the regular hbase shell. If it doesn't work, check Ambari UI that both master and region servers are running

3. Not necessary, but recommended to build your application with HDP HBase libraries. For maven include the HDP repo into your project


and set the corresponding version for HBase libraries like (for HDP 2.5)
