Namenode impossible to leave safemode

We have a big problem with Namenode that does not want to leave Safemode with the following error:

sudo -u hdfs hdfs dfsadmin -safemode leave

/usr/hdp/2.6.4.0-91/hadoop/conf/hadoop-env.sh: line 51: syntax error near unexpected token `export'

/usr/hdp/2.6.4.0-91/hadoop/conf/hadoop-env.sh: line 51: `export HADOOP_CLASSPATH=${HADOOP_CLASSPATH}${JAVA_JDBC_LIBS} '

safemode: Call From namenode/10.0.0.4 to namenode:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused

Any help please ?

We changed all the owner of the files to hdfs and the access to 775 in

var/log/hadoop/hdfs

-rw-r--r-- 1 hdfs hadoop 948 Oct 30 16:11 hadoop-hdfs-datanode-namenode.out

Nothing on the logs. The IPtables and the SELINUX are deactivated.

Are you running that command only our NameNode? If so, your NameNode process is probably not running at all.
