      Java version 1.7.0.101

    • Severity:
      Normal

      Description

      Cassandra returns the error 'Cassandra 2.0 and later require Java 7u25 or later.' when run using java 7 versions greater than 7u101. This is due to using string comparisons for the versions in the cassandra-env.sh file.

      The current cassandra-env.sh script contains the following code which uses string comparisons (I.e. 101 is less than 25 if you compare as strings)

      if [ "$JVM_VERSION" \< "1.8" ] && [ "$JVM_PATCH_VERSION" \< "25" ] ; then
      echo "Cassandra 2.0 and later require Java 7u25 or later."
      exit 1;
      fi

      To properly handle the numeric version comparison the -lt operator should be used. For example

      if [ "$JVM_VERSION" \< "1.8" ] && [ "$JVM_PATCH_VERSION" -lt "25" ] ; then
      echo "Cassandra 2.0 and later require Java 7u25 or later."
      exit 1;
      fi
