RE: Issue with Querying External Hive Table created on hbase
I am not sure about your question. Do you mean the query runs very fast if you run like 'select * from hbase_table', but very slow for 'select * from hbase where row_key = ?' I think it should be the other way round, right?

Re: Issue with Querying External Hive Table created on hbase
You can check the exact reason from job log, but generally, it's caused by missing libs in auxlib conf. Thar includes hive-hbase-handler.jar, hbase-*.jar, guava-*.jar, zookeeper-*.jar, etc. ,varying the version of your hive and hbase.
