Matt Burgess commented on HIVE-4806:
------------------------------------
Alan,
Thanks for the feedback! I will incorporate them and submit a new patch, here
are a few notes:
- HiveConnection.setReadOnly - Oops! I blindly applied my Hive 1 changes across
to Hive 2. If HS2 supports both modes, I will update the patch to maintain the
appropriate state.
- HiveDatabaseMetaData.supportsResultSetConcurrency - I have not tested this
but I will try, do you know of existing test scripts that would educe this
behavior? Alternatively, is it more appropriate to return false for Hive / HS2?
- HiveResultsSetMetaData.getColumnTypeName - I'm not really sure about these, I
inherited a bit of this code. I did find references in MetaStoreUtils:
https://github.com/apache/hive/blob/075e02ea6de25958de2820d73b7865e7f9d56189/metastore/src/java/org/apache/hadoop/hive/metastore/MetaStoreUtils.java
but I'm not sure this is germane to HiveResultsSetMetaData. I can surely remove
these if appropriate to do so.

> Third-party client software such as Pentaho Data Integration (PDI) uses many
> different JDBC API calls when interacting with JDBC data sources. Several of
> these calls have not yet been implemented in the Hive and Hive 2 drivers and
> by default will throw "Method not supported" SQLExceptions when there could
> be default implementations instead.
