(Updated Nov. 17, 2015, 11:25 a.m.)


Review request for Ambari, Alejandro Fernandez, Jayush Luniya, and Nate Cole.


Changes
-------

Revised to an egrep command to condense into a single loop.


Bugs: AMBARI-13912
    https://issues.apache.org/jira/browse/AMBARI-13912


Repository: ambari


Description
-------

When Ranger is configured to use PostgresSQL, the HDFS NameNode will not startup correctly,
complaining about missing class drivers. The root of the problem is that {{hadoop-env.sh}}
adds JDBC drivers for Oracle and MySQL only.

{code}
# Add libraries required by oracle connector
for jarFile in `ls /usr/share/java/*ojdbc* 2>/dev/null`
do
  JAVA_JDBC_LIBS=${JAVA_JDBC_LIBS}:$jarFile
done
{code}

Ranger needs the following driver support:
||DB Type||JDBC Driver JAR Name||Minimum Supported Version||Driver Reference Link
|Mysql|mysql-connector-java.jar|MySQL 5.6|[Link|http://dev.mysql.com/doc/connector-j/en/connector-j-versions.html]
|Oracle|ojdbc6.jar or ojdbc7.jar|Oracle 11g|[Link|http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html]
|Postgres|postgresql.jar|Postgres 8.4|[Link|https://jdbc.postgresql.org/documentation/84/setup.html#build]
|MS-SQLServer|sqljdbc4.jar|SQL Server 12|[Link|https://msdn.microsoft.com/en-us/sqlserver/aa937724.aspx]

Testing
-------

Verified that matching JARs for SQL Server and PostgreSQL were added to the classpath.


Thanks,
