I have Sqoop 1.4.2 installed Running sqoop version returns
Sqoop 1.4.2 git commit id Compiled by ag on Tue Aug 14 17:37:19 IST 2012 When I tried to run a sqoop import-all-tables I got "Unknown SQL Data type: -9". From the discussion below, nvarchar should be supported in this version of sqoop, please advise?

If you need to build entire distribution (like the one that is offered in download page) including (almost) all dependency jars you need to run command "ant -Dhadoopversion=$hadoopVersion tar", where $hadoopVersion is your hadoop version. Supported values are 20, 23, 100 and 200. > 2.

You might find more information about incremental imports in Sqoop documentation: http://sqoop.apache.org/docs/1.4.2/SqoopUserGuide.html#_incremental_imports > Thank you.
