FAQ for Hbase updated
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

Ok I see the two bugs you said we where waiting on have been committed to
the trunk what else are we waiting on to be able to do map reduce with
hbase?

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