Running Raft / HBASE-12259 test-apps standalone

[Justin Santa Barbara <ju...@fathomdb.com>]

I'm very interested in the Raft implementation (in particular, whether
it can be reused elsewhere, given that this effort seems likely to
produce the canonical Raft implementation for Java).  I'd like to try
it standalone, but I'm not yet having much success.

I start a cluster of 3 servers (N=0,1,2):

java -cp "conf:hbase-consensus/target/hbase-consensus-2.0.0-SNAPSHOT.jar:hbase-consensus/target/dependency/*"
org.apache.hadoop.hbase.consensus.server.LocalConsensusServer -region
1 -servers 127.0.0.1:10000,127.0.0.1:10001,127.0.0.1:10002 -debug
DEBUG -localIndex ${N}

And then I try running the load-test client:

java -cp "hbase-consensus/target/hbase-consensus-2.0.0-SNAPSHOT.jar:hbase-consensus/target/dependency/*"
org.apache.hadoop.hbase.consensus.client.QuorumLoadTestClient -region
1 -servers 127.0.0.1:10000,127.0.0.1:10001,127.0.0.1:10002

That gives an immediate NPE at
org.apache.hadoop.hbase.consensus.quorum.QuorumInfo.populateInternalMaps(QuorumInfo.java:315).

Are there any docs on how to get started playing with running this
branch? Thanks!
