Added support to access Hbase over REST

[MansurAshraf]

Modified HBaseTemplate to support accessing HBase over REST by wrapping HBase rest client (http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/rest/client/package-summary.html). This is useful in environments where HBase is not directly accessible through Zookeeper and needs to be accessed over HTTP/REST. Changes are backward compatible and should not effect existing behavior.

Hi,

Thanks for the pull-request. I took a look at it and have a couple of comments.

We are in the process of changing over to a multi-module build breaking out any spring-batch related code into a separate module to manage dependencies better. So it might make more sense to wait until that is done before reworking your pull-request. Shouldn't be too difficult since you mostly have new code.

Looks like your url change to the build.gradle got pulled in by accident. Also we should leave the hd.fs port as 8020 in test.properties.

Would be nice if we could run the Hbase REST tests conditionally until we have time to add a REST server config to the CI builds.

Also, all current code uses tabs instead of spaces for indentation so it would be better if you used tabs as well. Much easier for diffs as well.

Hi,

Can I help in any way?
I also have my own implementation using a connection pool and this change would be helpful.

Thanks,
Bruno

Hi Bruno,

If you have some ideas, a pull request against master is more than welcome. Otherwise open a JIRA ticket here: https://jira.springsource.org/browse/SHDP
