cassandraunit сбой сразу

Question

Я пытаюсь запустить тесты unit cassandra на маленькой машине с ванилью ubuntu 12, но тест или сбой сразу после этого не дают мне никакой информации. Когда я пытаюсь его в РЕПЛ я получаю следующее:

scala> org.cassandraunit.utils.EmbeddedCassandraServerHelper.startEmbeddedCassandra()

Answer 1

Оказывается, мне нужно> 4 Гб оперативной памяти для модульного тестирования. Начиная с env JAVA_OPTS="-Xmx5G" sbt test решил.

Answer 2

с первого взгляда проблема, кажется, multple SLF4J переплета. У вас есть несколько банок с регистратором slf4j.

SLF4J: Class path contains multiple SLF4J bindings. 
SLF4J: Found binding in [jar:file:/root/.ivy2/cache/ch.qos.logback/logback-classic/jars/logback-classic-1.1.2.jar!/org/slf4j/impl/StaticLoggerBinder.class] 
SLF4J: Found binding in [jar:file:/root/.ivy2/cache/org.slf4j/slf4j-log4j12/jars/slf4j-log4j12- 1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class] 

Удалите любой из них и повторите попытку.
