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

             Summary: set hadoop.log.dir and hadoop.id.str when starting secure datanode so it writes the logs to the correct dir by default
                 Key: HDFS-4541
                 URL: https://issues.apache.org/jira/browse/HDFS-4541
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode, security
    Affects Versions: 2.0.3-alpha
            Reporter: Arpit Gupta
            Assignee: Arpit Gupta


currently in hadoop-config.sh we set the following

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

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
