Aaron Kimball updated MAPREDUCE-1168:
-------------------------------------

    Attachment: MAPREDUCE-1168.2.patch

Thanks for reviewing, Tom.

I agree on the renames of ImportOptions -> SqoopOptions and ExportError -> ExportException.
I had forgotten that exceptions with names ending in "Error" have an implied semantic meaning.
For consistency, I've also renamed ImportError to ImportException. 

You'll need to do the following in the subversion tree after applying this patch:
{code}
svn mv --force src/contrib/sqoop/src/java/org/apache/hadoop/sqoop/ImportOptions.java src/contrib/sqoop/src/java/org/apache/hadoop/sqoop/SqoopOptions.java

svn mv --force src/contrib/sqoop/src/java/org/apache/hadoop/sqoop/util/ImportError.java src/contrib/sqoop/src/java/org/apache/hadoop/sqoop/util/ImportException.java

svn mv --force src/contrib/sqoop/src/test/org/apache/hadoop/sqoop/TestImportOptions.java src/contrib/sqoop/src/test/org/apache/hadoop/sqoop/TestSqoopOptions.java
{code}

AutoInputFormat is currently based on the old API; until this is ported, it's incompatible
with the new API (which Sqoop tries to use as much as possible). Definitely worth keeping
in mind for the future though, once streaming is moved to the new API. I've copied the magic-number
test from AutoInputFormat into {{isSequenceFiles()}}. Note that this means that any text file
beginning with the characters "SEQ" is going to be misinterpreted as a SequenceFile now. This
case is hopefully rare.. we can address it when it comes up in practice?

This patch is also resync'd to trunk.

> Sqoop can import from a database into HDFS. It's high time it works in reverse too.
