-----------------------------------
Summary: quorumVerifier is null when creating a QuorumPeerConfig
from parsing a Properties object
Key: ZOOKEEPER-1864
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1864
Project: ZooKeeper
Issue Type: Bug
Reporter: some one
Assignee: some one
Fix For: 3.5.0
This bug was found when using ZK 3.5.0 with curator-test 2.3.0.
curator-test is building a QuorumPeerConfig from a Properties object and then
when we try to run the quorum peer using that configuration, we get an NPE:
2014-01-19 21:58:39,768 [myid:] - ERROR [Thread-3:TestingZooKeeperServer$1@138]
- From testing server (random state: false)
java.lang.NullPointerException

at
org.apache.curator.test.TestingZooKeeperServer$1.run(TestingZooKeeperServer.java:134)
at java.lang.Thread.run(Thread.java:722)
The reason that this happens is because QuorumPeerConfig:parseProperties only
peforms a subset of what 'QuorumPeerConfig:parse(String path)' does. The exact
additional task performed is the dynamic config backwards compatibility check:
// backward compatibility - dynamic configuration in the same file as static
configuration params
// see writeDynamicConfig() - we change the config file to new
format if reconfig happens
if (dynamicConfigFileStr == null) {
configBackwardCompatibilityMode = true;
configFileStr = path;................
parseDynamicConfig(cfg, electionAlg, true);
checkValidity();................
}
