I'm using CDH5.0.2(automated install). Single node hadoop installation. CDH manager is installed on a different node.
I follow this guide to install JDBC driver for SQL server.
after copying sqljdbc4.jar to /var/lib/sqoop2, i restarted both sqoop2 and hue service. but when i create a new sqoop transfer job using hue's web ui, the jdbc driver class can't find any sql server driver. When i typed in "sql" in the jdbc driver class, it can only find MySql and PostGres Sql driver. it cannot find SQL server driver.
I tried changing the owenership(to sqoop2:sqoop2) and also the permission to the sqljdbc4.jar(to 644) to match that is of postgresql-9.0-801.jdbc4.jar in /var/lib/sqoop2, and restart the sqoop2 and hue service again, and still no luck. It still can't seem to find SQL server driver when i typed in SQL. What should be the value of this field for MS SQL Server??
I would really appreciate any help. I've ben evaluating CDH5, and can't seem to figure out this problem.

Same problem here baj - haven't found any documentation that correctly speaks to a CDH5.02 install. We're going to need some help here please!

Just a few questions to help me understand what you're seeing:

in my case, i'm using parcel, i'm not getting any exception. everything seems to install correctly(extracting jand copying sqljdbc4.jar to /var/lib/sqoop2).
I restarted both sqoop2 and hue service. but when i create a new sqoop transfer job using hue's web ui, the jdbc driver class can't find any sql server driver. When i typed in "sql" in the jdbc driver class, it can only find MySql and PostGres Sql driver. it cannot find SQL server driver.
I tried using sqoop1 via command line, it works, but not in sqoop2.

Ah are you referring to the Hue UI? You should be able to add the SQL Server JDBC driver even though it's not part of the autocompletion list. That's local to Hue. I believe this is: com.microsoft.sqlserver.jdbc.SQLServerDriver.

Thanks for your help! My question is around installation - what directory should I put the sqljdbc4.jar file in? This is a stock Cloudera install (parcels) done just last week on a 3-node CentOS cluster. It appears most things are installed under: /opt/cloudera/parcels/CDH-5.0.1-1.cdh5.0.1.p0.47, but I've found other bits and pieces elsewhere. Or even better, and I do this from Cloudera Cluster Manager?
When I use HUE/Scoop2 UI and attempt to define a new connection, I get this error on the JDBC Driver Class field: Can't load specified driver. The value I put in this field is "com.microsoft.sqlserver.jdbc.SQLServerDriver".
I've put sqljdbc4.jar in the /opt/cloudera/parcels/CDH/lib/sqoop/lib directory.

Two more details: I've put sqljdbc4.jar only on the one node I've logged into with Hue - it's not on the other nodes yet (if that matters?). Also, I've restarted the Hue and Scoop2 processes via Cloudera Manager.

The sqljdbc4.jar file should be on the node running the Sqoop2 server. It should be put in the directory /var/lib/sqoop2. Then, you just need to restart the Sqoop2 server and it should be available.
The UI may not autocomplete it, but it's there.

I've followed the instructions listed in this thread and I still receive the same error message, "Can't load specified driver". Are there any other ways to troubleshoot this problem?
