Hi Matt,
When I try to change to jdbc:hive2://, I get a different error set of errors.
>Error getting Hive connection
>org.apache.commons.dbcp.SQLNestedException: Cannot create
>PoolableConnectionFactory (Could not open client transport with JDBC Uri:

>Caused by: java.sql.SQLException: Could not open client transport with JDBC

I am thinking you are right in that it is an issue with my connection URL. Is
there some command I can run that will generate this for me? Or a specific
place I should look? The only mention of a url in hive-site.xml that I see is:
<property>
<name>hive.metastore.uris</name>
<value>thrift://server:port</value>
</property>

Subject: Re: SelectHiveQL Error
Andrew is correct. Although the HiveServer
1 driver is included with the NAR, the HiveConnectionPool is hardcoded to use
the HiveServer 2 driver (since the former doesn't allow for simultaneous
connections and we are using a connection pool :) the scheme should be
jdbc:hive2:// not hive.
If that was a typo and you are using the correct scheme, could you provide your
configuration details/properties?
Thanks,
Matt

Sorry about the formatting. Any ideas? Is there some way I can edit the Hive
Nar file?

Subject: Re: SelectHiveQL Error
Dan,
That is a catch-all error returned when (in case probably) something is
misconfigured. Are there more error lines below that in the log?
The driver class and all its dependencies are present in the Hive NAR, so there
is likely an underlying error that, while being propagated up, returns the
generic (and misleading) error message you describe.
Regards,
Matt
