    Hi,

    Im trying to do an incremental import using the Sanbox 2.1 and a Microsoft SQL Server (AdventureWorks database). For the incremental import i’m using the following command:

    sqoop import --connect "jdbc:sqlserver://192.168.40.133:1434;database=AdventureWorksLT2012;username=test;password=test" --table ProductModel --hive-import --check-column ProductModelID --incremental append --last-value 128 -- --schema SalesLT

    As you can see in the error message below, the select statement “SELECT MAX([SalesLT].[ProductModelID]) FROM ProductModel” is not constructed the right way.

    The schema name is added to the column without the table name and the table name in the FROM clause is missing the schema name…

    Warning: /usr/lib/sqoop/../accumulo does not exist! Accumulo imports will fail.
    Please set $ACCUMULO_HOME to the root of your Accumulo installation.

    Any help is appreciated.

    Thank you!

    PS.
    Importing a full table is working fine.

    sqoop import --connect "jdbc:sqlserver://192.168.40.133:1434;database=AdventureWorksLT2012;username=test;password=test" --table ProductModel --hive-import -- --schema SalesLT
