Brandon Williams updated CASSANDRA-8890: ---------------------------------------- Reviewer: Michael Shuler > Enhance cassandra-env.sh to handle Java version output in case of OpenJDK > icedtea" > ---------------------------------------------------------------------------------- > > 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 > Priority: Minor > Labels: conf, icedtea > Fix For: 3.0 > > Attachments: 8890-v2.txt, trunk-8890.patch, trunk-8890.txt > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
