Why Impala not working on hbase table? - hadoop

Question

I create an external table B of hbase table A using hive. I can successfully access the data of B.Then I followed the official guide to type in Imapla Shell:
invalidate metadata B;
And then I query this external table B in Impala Shell:
select * from B limit 4;
but it outputs:
ERROR: RuntimeException: couldn't retrieve HBase table (mv_p2pusers) info:
Enable/Disable failed
Here are some logs related:

It seems the hbase table B is either enabled nor disabled,very strange.I googled around,Is this related to the hbase security issues or the impala version problem?
Did anybody encountered the same problems?How to solve this?Thanks in advance.

Answer 1

Enable HBase service from Impala Configuration.
You can do it from Cloudera manager, Imapala->configuration
search from "Hbase" and enable the service.
