Tyler Hobbs created CASSANDRA-7137: -------------------------------------- Summary: Check for Java >= 1.7 in bin/cassandra Key: CASSANDRA-7137 URL: https://issues.apache.org/jira/browse/CASSANDRA-7137 Project: Cassandra Issue Type: Improvement Components: Core Reporter: Tyler Hobbs Priority: Minor Fix For: 2.0.8
Since we don't currently check for a Java version >= 1.7 but use flags that were introduced in 1.7, you can get cryptic error messages when starting Cassandra with 1.6. For example: {noformat} ~/cassandra $ JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.26/ bin/cassandra -f Unrecognized VM option 'StringTableSize=1000003' Could not create the Java virtual machine. {noformat} We had some code in 1.2 to detect the java version and change flags depending on that, so that would be a good starting point: https://github.com/apache/cassandra/blob/cassandra-1.2/conf/cassandra-env.sh#L209 -- This message was sent by Atlassian JIRA (v6.2#6252)
