Subject Data export to SQL Server fails with MAPRED_EXEC_0017:Error occurs during extractor run
Date Mon, 09 Sep 2013 12:39:34 GMT

Hello all!

I have installed the latest CDH + Manager version from Cloudera on a freshly installed Ubuntu
12.04 virtual host.

I have successfully imported a table from SQL Server into HDFS text files.

When I try to export it again to a new table with the exact same schema as the original I
get the following error in the logs:
