--------------------------------------
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
