[jira] [Created] (HIVE-2957) JDBC getColumns() fails on a TIMESTAMP
column
JDBC getColumns() fails on a TIMESTAMP column
---------------------------------------------
Key: HIVE-2957
URL: https://issues.apache.org/jira/browse/HIVE-2957
Project: Hive
Issue Type: Bug
Components: JDBC
Affects Versions: 0.8.1, 0.9.0
Reporter: Bharath Ganesh
Assignee: Bharath Ganesh
Priority: Minor
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)

Bharath Ganesh updated HIVE-2957:
---------------------------------
Attachment: HIVE-2957.patch
Added support for TIMESTAMP column on the JDBC driver. I am not 100% sure of the precision and scale. Please do verify. I tested the sanity and I am able to retrieve a column upto nano-second precision.
