Paul Bayliss created CASSANDRA-11832: ----------------------------------------
Summary: Cassandra 2.1x and 2.2.x does not start with java 7u101
Key: CASSANDRA-11832
URL: https://issues.apache.org/jira/browse/CASSANDRA-11832
Project: Cassandra
Issue Type: Bug
Components: Lifecycle
Environment: Linux xxxxxx 3.13.0-63-generic #103-Ubuntu SMP Fri Aug 14
21:42:59 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Java version 1.7.0.101
Reporter: Paul Bayliss
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
