That command must be run as the HDFS superuser (usually "hdfs"). So, try it this way:

sudo -u hdfs hdfs dfsadmin -safemode leave

I am having this issue.

Tried with the command you have given however there is one more error which says -

Java HotSpot(TM) 64-Bit Server VM warning: Insufficient space for shared memory file:
<some value>
Try using the -Djava.io.tmpdir= option to select an alternate temp location.

i am not sure about setting this Djava.io.tmpdir, can you please help ?
