Embedded server startup error with Cassandra 3.10

[amichair]

When upgrading Cassandra from 3.9 to 3.10 (and cassandra-unit 3.1.3.2), the embedded server fails to start:

java.lang.NullPointerException: null
        at org.apache.cassandra.config.DatabaseDescriptor.createAllDirectories(DatabaseDescriptor.java:1152)
        at org.cassandraunit.utils.EmbeddedCassandraServerHelper.mkdirs(EmbeddedCassandraServerHelper.java:349)
        at org.cassandraunit.utils.EmbeddedCassandraServerHelper.cleanupAndLeaveDirs(EmbeddedCassandraServerHelper.java:321)
        at org.cassandraunit.utils.EmbeddedCassandraServerHelper.startEmbeddedCassandra(EmbeddedCassandraServerHelper.java:122)
        at org.cassandraunit.utils.EmbeddedCassandraServerHelper.startEmbeddedCassandra(EmbeddedCassandraServerHelper.java:91)

        at org.cassandraunit.utils.EmbeddedCassandraServerHelper.startEmbeddedCassandra(EmbeddedCassandraServerHelper.java:58)
...

The configuration seems to no longer be applied (it is null) - perhaps Cassandra changed something about its configuration initialization that broke this.

Hi team.
This is improved in 3.1.4.0-SNAPSHOT. When 3.1.4.0 will be released?

I found a workaround by calling DatabaseDescriptor.daemonInitialization() after creating the CassandraUnit instance.

@nevillelyh what exactly did you do? There is no CassandraUnit class to make an instance of.
Before startEmbeddedCassandra it throws a ConfigurationException. After, and it's too late.

We are facing the same issue . It works if we use 3.1.4.0-SNAPSHOT . We cannot use a SNAPSHOT dependency on our production code .is this part of any ongoing milestone ? Can you please let us know when it will be released.
@nevillelyh @OrangeDog - The changes you mentioned are part of EmbeddedCassandraServerHelper.java in 3.1.4.0-SNAPSHOT right ? Which other version of Cassandra unit has this fix ?

[nevillelyh]

Sorry I ended up not using cassandra-unit since we ran into other problems that are not easily fixable.

This seems to work around the problem.

      try {
        EmbeddedCassandraServerHelper.startEmbeddedCassandra(timeout);
      }
      catch (NullPointerException e) {
        DatabaseDescriptor.daemonInitialization();
        EmbeddedCassandraServerHelper.startEmbeddedCassandra(timeout);
      }

can you publish new JAR with this fix?

@jsevellec As 3.3.0.1 broke other things (#247) can you please release 3.1.4.0.

[amichair]

This issue no longer occurs in release 3.3.0.2, so I'm closing it.
