An exception or error caused a run to abort: Unable to start EmbeddedCassandra[name='cassandra-2', version='3.11.6']

I am using embedded-cassandra in my unit tests (Scalatest). When I try to run all the test cases as batch, I get error

An exception or error caused a run to abort: Unable to start EmbeddedCassandra[name='cassandra-2', version='3.11.6']

What I might be doing wrong? As the trace says cassandra-2, it seems that another instance of Cassandra is already running? Could it be that the tests are running simultaneously? What is the way to run tests serially in Intellij/Scalatest?

This answers mentions that Scalatest would run suits in parallel which might be causing the port conflict issue. Is there a way to avoid port conflict in embedded-cassandra or run suites serially? - How to run tests in a class sequentially in ScalaTest?

Solution

  • You can try to use random ports to solve your issue:

    EmbeddedCassandraFactory cassandraFactory = new EmbeddedCassandraFactory();
cassandraFactory.setPort(0);
cassandraFactory.setSslPort(0); // if SSL client options enabled
cassandraFactory.setRpcPort(0);
cassandraFactory.setJmxLocalPort(0);
cassandraFactory.setStoragePort(0);
cassandraFactory.setSslStoragePort(0); // // if SSL server options enabled
