RE: FAILED: Hive Internal Error: java.lang.RuntimeException(java.net.ConnectException
Hi Sagar,

Show tables and select * from Table_Name just dump data.

here you don't have reducers.

but for count(*) operation reducers got assign the job to do.
Check out you network settings ans pass the IP address to by pass proxy.

Regards
Yogesh Kumar Dhari
