> Key: CASSANDRA-8890
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8890
> Project: Cassandra
> Issue Type: Improvement
> Components: Config
> Environment: Red Hat Enterprise Linux Server release 6.4 (Santiago)
> Reporter: Sumod Pawgi
> Assignee: Brandon Williams

> Fix For: 3.0

> Where observed -
> Cassandra node has OpenJDK -
> java version "1.7.0_09-icedtea"
> In some situations, external agents trying to monitor a C* cluster would need
> to run cassandra -v command to determine the Cassandra version and would
> expect a numerical output e.g. java version "1.7.0_75" as in case of Oracle
> JDK. But if the cluster has OpenJDK IcedTea installed, then this condition is
> not satisfied and the agents will not work correctly as the output from
> "cassandra -v" is
> /opt/apache/cassandra/bin/../conf/cassandra-env.sh: line 102: [: 09-icedtea:
> integer expression expected
> Cause -
> The line which is causing this behavior is -
> jvmver=`echo "$java_ver_output" | grep '[openjdk|java] version' | awk -F'"'
> 'NR==1 {print $2}'`
> Suggested enhancement -
> If we change the line to -
> jvmver=`echo "$java_ver_output" | grep '[openjdk|java] version' | awk -F'"'
> 'NR==1 {print $2}' | awk 'BEGIN {FS="-"};{print $1}'`,
> it will give $jvmver as - 1.7.0_09 for the above case.
> Can we add this enhancement in the cassandra-env.sh? I would like to add it
> myself and submit for review, but I am not familiar with C* check in process.
> There might be better ways to do this, but I thought of this to be simplest
> and as the edition is at the end of the line, it will be easy to reverse if
> needed.
