Subject [jira] [Commented] (HIVE-538) make hive_jdbc.jar self-containing
Date Tue, 29 Apr 2014 02:23:15 GMT


Thejas M Nair commented on HIVE-538:

The hadoop dependencies for jdbc client are needed only when kerberos authentication is used.
However, it is a small set of hadoop jars that are needed, and their transitive dependencies
are not needed. In case of hadoop 1.x, it is just hadoop-core*jar that is needed. I am not
sure of the exact dependency in hadoop-2.x .

I am fine with option 1. But if we can do option 3, with the minimal set of hadoop jars requried,
that would be awesome.

> Currently, most jars in hive/build/dist/lib and the hadoop-*-core.jar are required in
the classpath to run jdbc applications on hive. We need to do atleast the following to get
rid of most unnecessary dependencies:
> 1. get rid of dynamic serde and use a standard serialization format, maybe tab separated,
json or avro
> 2. dont use hadoop configuration parameters
> 3. repackage thrift and fb303 classes into hive_jdbc.jar
