>                 URL: https://issues.apache.org/jira/browse/HBASE-13360
>             Project: HBase
>          Issue Type: Improvement
>          Components: Consensus
>    Affects Versions: HBASE-12259
>            Reporter: Justin SB
>            Priority: Minor

> 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).
> 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!
