Use 'exec' to invoke catalina.sh in HttpFS's httpfs.sh
------------------------------------------------------
Key: HDFS-3097
URL: https://issues.apache.org/jira/browse/HDFS-3097
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 0.23.1
Reporter: Herman Chen
Without it shell spawns a new process, which defeats the purpose when you would
like to run it in the foreground with "httpfs.sh run", which eventually invokes
"catalina.sh run".
