Hello,
I attempted HBase replication for the first time and am trying to
understand how it works.
I have three HBase clusters each with their own ZK ensemble, A, B, C. I
wanted to have complete acyclical replication between all 3 clusters, so I
added B as a peer of A, C as a peer of B, A as a
I had the same issue. I ended up writing a coprocessor that did this under
the BatchMutate hood using a special attribute in the Put operation, and
that increased performance significantly to be almost equal to the regular
batchMutate(Put) version.

Hello,
I'd like to write a similar coprocessor to the example
RegionObserverExample at
http://www.3pillarglobal.com/insights/hbase-coprocessors : that is, a scan
coprocessor which intercepts and selectively filters scan results.
My problem is, I need to be able to filter out Results based on a
Z for example.

Hello all,
So, I wrote a Java application for HBase that does a partitioned full-table
scan according to a set number of partitions. For example, if there are 20
partitions specified, then 20 separate full scans are launched that cover
an equal slice of the row identifier range.
The rows are
