Hello, I sent this email to the users list a few days ago but no one there
seems to be able to help, so I am trying the dev list. I am working on an
application that queries and interacts with hive using the JDBC API. In many
other cases, using a JDBC connection pool such as commons-dbcp or BoneCP or
HikariCP is a recommended practice and results in much better performance. All
of the examples I’ve found of using accessing Hive through the JDBC API (such
as
https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients#HiveServer2Clients-JDBCClientSampleCode)
use a raw JDBC connection to Hive directly. A few questions:
1. Should hive work with connection pools such as commons-dbcp, BoneCP, or
HikariCP?
* Note: I have tried all BoneCP and HikariCP, and cannot seem to get
either to work because HiveConnection.setReadOnly throws a
java.sql.SQLException saying “Method not supported”. I am using hive 0.14.0.
2. Do you recommended using a JDBC connection pool for interacting with hive
from an application that will execute many repeated and concurrent
queries/statements?
Also, just to be clear, I am not asking about configuring the Hive metastore to
use a connection pool to connect to its underlying database (MySQL, PostgreSQL,
etc), but about using a connection pool to interact with and query Hive through
the JDBC api from an application.
Thank you,
David McWhorter
