I believe -Dhadoop2 is also redundant.
mvn clean install -Dhadoop.version=2.3.0 should be sufficient

The problem is that seqdirectory doesn't do what you want. From the
documentation page:
The output of seqDirectory will be a Sequence file Text, Text of
all documents (/sub-directory-path/documentFileName, documentText).
Please see
Since these very names were used in the Example, I thought nothing more
was required to be done in creating sequence file.
What further steps are needed? Please suggest simple shell command.

Kevin,
From trunk, can you build mahout for hadoop2 using this command:
mvn clean package -DskipTests=true -Dhadoop2.version=YOUR_HADOOP2_VERSION
Then can you verify that you have the right hadoop jars with the following
