Description

currently in hadoop-config.sh we set the following

HADOOP_OPTS="$HADOOP_OPTS -Dhadoop.log.dir=$HADOOP_LOG_DIR"
HADOOP_OPTS="$HADOOP_OPTS -Dhadoop.id.str=$HADOOP_IDENT_STRING"

however when this file is sourced we dont know whether we are starting a secure data node.

In the hdfs script when we determine whether we are starting secure data node or not we should also update HADOOP_OPTS
