Misconfiguration in cassandra-env.sh does not report any errors.

Once I have misconfigured the file /etc/cassandra/cassandra-env.sh. I changed the MAX_HEAP_SIZE="1500M" and did not change the HEAP_NEWSIZE="350M", letting it commented. Now I know that if you change one, you MUST change the other, but even knowing that it is written in the file in comments, I think some error message should appear to the user.

When it occured to me, I looked in the files /var/log/cassandra/system.log and debug.log and there wasn't any line telling about the error. The command {{ #service cassandra start }} is just responseless.

There should be some warning in the logs and maybe in the stdout, warning that the interpretation of the cassandra-env.sh parameters was wrong.

I attached the file in which the error happens.
