-Re: Does HBase 0.92 Rest client supports coprocessor execution?
Andrew Purtell 2012-09-03, 22:19
You are correct, it is not supported.
I think direct invocation of coprocessors is out of scope of the REST API,
because coprocessorExec is an arbitrary remote method call. That is the
domain of SOAP/WS. There is no WS API for HBase at this time (and none
planned that I know of).
