Subject connection pooling for hive JDBC client
Date Wed, 03 Jun 2015 18:04:34 GMT
Hello, 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
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
