[jira] [Created] (CASSANDRA-4401) If processor is missing from /proc/cpuinfo, cassandra will not start

Andy Cobley created CASSANDRA-4401:
--------------------------------------

             Summary: If processor is missing from /proc/cpuinfo, cassandra will not start
                 Key: CASSANDRA-4401
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4401
             Project: Cassandra
          Issue Type: Bug
          Components: Packaging
    Affects Versions: 1.1.1
            Reporter: Andy Cobley
            Priority: Minor


cassandra.env.sh does an egrep on /proc/cpuinfo in order to find the number of processors on the system.  If /proc/cpuinfo does not contain a processor :# line then the script will fail because of a divide  by 0 error.  Changing the Linux section of cassandra.env.sh to:


Linux)
            system_memory_in_mb=`free -m | awk '/Mem:/ {print $2}'`
            system_cpu_cores=`egrep -c 'processor([[:space:]]+):.*' /proc/cpuinfo`
            if [ "$system_cpu_cores" -lt "1" ]
            then
               system_cpu_cores="1"
            fi
is a possible fix
