Arsalan, > Can you provide example of coprocessors using 0.92
The unit tests provide some limited examples: http://svn.apache.org/viewvc/hbase/branches/0.92/src/test/java/org/apache/hadoop/hbase/coprocessor/ A complete example implementation is the AccessController in 0.92: http://svn.apache.org/viewvc/hbase/branches/0.92/security/src/main/java/org/apache/hadoop/hbase/security/access/ This Coprocessor implements the MasterObserver and RegionObserver interfaces. It also extends RPC with an Endpoint (a custom RPC protocol), as AccessControllerProtocol. > or any other informative link to use? I need to recover some content on Coprocessor development posted to a blog a while back. It will appear on the HBase wiki when I can get it back. In the meantime, there is: http://www.slideshare.net/ghelmling/new-hbase-features-coprocessors-and-security Best regards, - Andy Problems worthy of attack prove their worth by hitting back. - Piet Hein (via Tom White) ----- Original Message ----- > From: Arsalan Bilal <[email protected]> > To: [email protected] > Cc: > Sent: Tuesday, December 13, 2011 7:02 AM > Subject: Re: hbase coprocessor availability issue in 0.90.4 > > @Harsh: How can we implement coprocessors in hbase?
