Andrew Bayer 81608e42b6 SQOOP-110. Allow empty strings to represent NULL. This change modifies the ClassWriter implementation to provide support for interpeting empty strings as NULL values for datatypes other than String. For String datatype, an explicit string 'null' is interpreted as NULL value and empty string is not. This is because certain databases distinguish between NULL and empty strings. The clone implementation generated by ClassWriter has also been modified to make it more defensive against the presence of NULL values.

README.txt

= Welcome to Sqoop!

This is the Sqoop (SQL-to-Hadoop) tool. Sqoop allows easy imports and
exports of data sets between databases and HDFS.


== More Documentation

Sqoop ships with additional documentation: a user guide and a manual page.

Asciidoc sources for both of these are in +src/docs/+. Run +ant docs+ to build
the documentation. It will be created in +build/docs/+.

If you got Sqoop in release form, documentation will already be built and
available in the +docs/+ directory.


== Compiling Sqoop

Compiling Sqoop requires the following tools:

* Apache ant (1.7.1)
* Java JDK 1.6

Additionally, building the documentation requires these tools:

* asciidoc
* make
* python 2.5+
* xmlto
* tar
* gzip

To compile Sqoop, run +ant package+. There will be a fully self-hosted build
provided in the +build/sqoop-(version)/+ directory. 

You can build just the jar by running +ant jar+.

See the COMPILING.txt document for for information.

== This is also an Asciidoc file!
