Test failures on initial build

Hello,

I’m prototyping etcd to run our local service discovery.

I’m running Debian 8.0, and using the official Quay Docker image to run etcd.

I’ve started the docker single instance cluster using:

docker run -d -v /usr/share/ca-certificates/:/etc/ssl/certs -p 4001:4001 -p 2380:2380 -p 2379:2379 \
 --name etcd quay.io/coreos/etcd etcd \
 -name etcd0 \
 -advertise-client-urls http://${HostIP}:2379,http://${HostIP}:4001 \
 -listen-client-urls http://0.0.0.0:2379,http://0.0.0.0:4001 \
 -initial-advertise-peer-urls http://${HostIP}:2380 \
 -listen-peer-urls http://0.0.0.0:2380 \
 -initial-cluster-token etcd-cluster-1 \
 -initial-cluster etcd0=http://${HostIP}:2380 \
 -initial-cluster-state new

If I clone the latest coreos/jetcd and run mvn package, I get a test failure:

Tests run: 34, Failures: 2, Errors: 0, Skipped: 3, Time elapsed: 28.542 sec <<< FAILURE! - in TestSuite
testListCluster(com.coreos.jetcd.EtcdClusterClientTest)  Time elapsed: 0.013 sec  <<< FAILURE!
java.lang.AssertionError: Members: 1 expected [3] but found [1]
	at com.coreos.jetcd.EtcdClusterClientTest.testListCluster(EtcdClusterClientTest.java:33)

Is this a known issue?

Also, if I try to run it again, I get that same error, plus a new one:

testGetSortedPrefix(com.coreos.jetcd.EtcdKVTest)  Time elapsed: 0.034 sec  <<< FAILURE!
java.lang.AssertionError: expected [3] but found [4]
	at com.coreos.jetcd.EtcdKVTest.testGetSortedPrefix(EtcdKVTest.java:115)

So as a secondary issue, there may be a need to setup the environment properly.

Thank you, Dustin

Hello, @at88mph After you use testAddMember, there are 2 members in the term. For raft with 2 members, the cluster get a leader only after 2 members all vote to the candidate. You do not have another member, so the cluster get into a endless loop without a leader. The etcd can not work without a leader. You can use the run_etcd.sh to start a 3 nodes cluster for the test. The test is designed to run in the enviroment with 3 nodes that initized with run_etcd.sh.
