             Summary: Accessing Hive table via JDBC Interpreter - Slow
                 Key: ZEPPELIN-3308
             Project: Zeppelin
          Issue Type: Test
          Components: zeppelin-interpreter
    Affects Versions: 0.7.0
         Environment: Test environment
            Reporter: Mothilal
             Fix For: 0.7.0

Simple Hive query : Select * from <default.sampleTable> limit 25 yielded 
response for 

Hive Client : <1 sec

Zeppelin %JDBC(Hive) : 30 sec.

While analyzing the logs, I understand it was taking time to fetch metadata of 
schema and did the same even when configuration specified default schema. 
Ideally the performance should be close to hive client with little latency but 
not major. Please advise if current data fetch approach is optimized for hive 
jdbc queries.
