I made a start here: http://wiki.apache.org/lucene-hadoop/Hbase/MapReduce.
Of note, hbase+MR in TRUNK is broke, at least for hbase as source, until
the fixes for MapWritable and TableInputFormat go in (HADOOP-2244 and
HADOOP-2234).

I can code just about anything I need in php and java is some what the same
in code style so I can almost read and understand what its doing. What would
be help full is a sample map/reduce reading from one column write result
back to sec column script for hbase so I could work with it and build off
it. I seen the TestTableMapReduce.class but its a little over complex for me
to start with.

Fixed. Sorry about that.

P.S. Be sure to check out the hbase unit tests if you're looking for more
on how to write hbase-ise.

Can we get someone who has written java apps that work with hbase update
the example on this page
http://wiki.apache.org/lucene-hadoop/Hbase/FAQ
I thank there is some bugs in there that need to be addressed
example:
desc.addFamily(new HColumnDescriptor(new Text("content:"));there are 3
('s bit only 2 )'s and I get a error when I try to run this with
javacaddtable.java:22: ')' expected
desc.addFamily(new HColumnDescriptor(new
Text("content:"));
^
addtable.java:23: ')' expected
desc.addFamily(new HColumnDescriptor(new
Text("anchor:"));
I am new to java so bugs like the above make it that much harder to
understand and get hbase working with there tests
Thanks
Billy
