0.20 REST interface
I've been exploring HBase recently and had originally set up a 0.19
cluster for prototyping, heard that 0.20 has all sorts of performance
enhancements and setup another 0.20 cluster on a separate dev
environment. Everything appears to be working fine, excepting that
the REST API appears to be non-existent.
I'm not sure if I have to do anything special to make it work, but
from what I can tell there should be a servlet under
http://hbase-master:port/api/
However, whenever I access that it just loads up a directory listing of
META-INF/
WEB-INF/
If I try to access anything under /api/, it returns 404s.
The javadoc for org.apache.hadoop.hbase.rest doesn't appear to be
different from 0.19 (it does list the default port as 60050 instead of
60010), so I'm not sure if I am missing some new configuration or if
there is something else wrong.
None of the updates since the revision I built from seem to touch
org.apache.hadoop.hbase.rest, though some of them deal with stargate.
Is the old API gone?

That's fine. My 0.19.3 setup started up the rest server by default on
port 60010 (at least, I don't remember doing anything to turn it on)
so I had assumed the 0.20 one would as well. As you say, it's easy
enough to fire one up...

Hmm. I remember in old days that we used to deploy the REST api on the
master but that was shut off a while ago. Thought was that no one was using
it -- sorry (I don't have the hbase issue to hand) -- and its easy enough
putting up an explicit REST server if wanted.
I'll let the REST lads talk to how different new API is.

Ah, so the rest server doesn't start up on it's own anymore with 0.20?
I'm looking forward to messing around with stargate, but I already
have some stuff that works with the old REST interface, so I'd like to
make sure that's still working before moving on :).

Re: 0.20 REST interface

Run:
./bin/hbase rest
It outputs options.
For example:
./bin/hbase rest start
... will start it in current console (on port 60050 by default).
To start it as background process writing a pid, etc., do
./bin/hbase-daemon.sh start rest.
That said, REST story is interesting in 0.20.0 in that the 0.19.0 REST was
redone by Brian Beggs.
Then Andrew Purtell did a new fancy REST server as a contrib called stargate
(with help from Brian Beggs).
Documentation on the latter is in javadoc. There are still a few pieces
missing but they are arriving fast.
