Release v2.0.3

The following functionality was added in order to ensure executions of TPC-H benchmark with HDFS_FDW with small data size

1- Parametrised where clause push down
2- Enable remote estimates
3- Option to log remote SQL
4- Option to specify fetch size
5- Add test cases in regression for parametrised and non-parametrised where push-down

Overall, the quality and stability of HDFS_FDW is greatly improved with this release. The TPC-H benchmark can be executed with HDFS_FDW with small data size, we have tested with multiple GB's of data. The enhancements for pushing down aggregates, sorts and joins will come next and will enable HDFS_FDW to run TPC-H benchmark with large data size.

Release v2.0

The HDFS_FDW 2.0 release had added support for LDAP authentication method. This is achieved by using the JDBC interface and removing the thrift CLI. The hdfs_fdw now uses the JDBC driver and doesn't require the thrift CLI to connect with Hive/HDFS.
