Anoop Sam John commented on HBASE-2038:
---------------------------------------

Hi Alex,
    Thanks for your reply...  Yes I had seen your past comment..I am checking the trunk code
for the co processor for this work as of now...

What is your comment on my first comment, that the HRegionServer next(final long scannerId,
int nbRows) calls the co processor preScannerNext() by passing the RegionScanner. On this
we can not make a seek()..

Thanks
Anoop

> HBASE-2037 is a good candidate to be done as coprocessor. It also serve as a good goalpost
for coprocessor environment design -- there should be enough of it so region level indexing
can be reimplemented as a coprocessor without any loss of functionality.
