In addition to setting the inputformat and outputformat classes, there
seems to be an option to specify additional name,value pairs
in the jobconf ("-jobconf"). The input and output format classes need
additional arguments that are not set using the other streaming arguments.
One example is the list of columns to scan. Please have a look at the
"initJob" method in o.a.h.hbase.mapred.TableMap and
o.a.h.hbase.mapred.TableReduce as well as the junit test,
o.a.h.hbase.mapred.TestTableMapReduce for how these are used.
I have not used the streaming package so have not tried this myself.

Re: map/reduce with hbase

Please respond to
[EMAIL PROTECTED]
e.apache.org
Basically what I am trying to do is access hbase from php sense I do not
know java and have not found it fun to learn
I was looking around and found this
https://issues.apache.org/jira/browse/HADOOP-2171
but am unsure if it is what I thank it is looks like a way to access hbase
from a socket server I have coded socket server/client in the past in php
so
the question is how would I use this to get access from say php.
would I add this and rebuild the hbase file somehow?
Remember I am new to java so have vary little knowing on how to do stuff.
