> Steps to replicate:
> 1. Create a table with at least one column of type TIMESTAMP
> 2. Do a DatabaseMetaData.getColumns () such that this TIMESTAMP column is part of the
resultset.
> 3. When you iterate over the TIMESTAMP column it would fail, throwing the below exception:
> Exception in thread "main" java.sql.SQLException: Unrecognized column type: timestamp
> 	at org.apache.hadoop.hive.jdbc.Utils.hiveTypeToSqlType(Utils.java:56)
> 	at org.apache.hadoop.hive.jdbc.JdbcColumn.getSqlType(JdbcColumn.java:62)
> 	at org.apache.hadoop.hive.jdbc.HiveDatabaseMetaData$2.next(HiveDatabaseMetaData.java:244)
