Can you please tell me what is main work of this command mount -o remount,exec /tmp

I am using it when my hbase giving some errors but i don't know what is happening using this command. and i want know about /tmp directory , it is using whole directory or some folder in that particular directory?

my main doubt is one of my colleage wants to know that i am using this folder /tmp/hadoop-aemadmin/ or not? I am handling nutch hbase and solr but i am not sure in backend this folder is used or not and one more thing i used that command in which /tmp mentioned that's why i am confused may be using this above command , this folder is used Can anyone guide me ? how to identify this folder is used or not?
 


Hello @kKnockKnock,
Welcome to the Linux.org forums,
this question was asked 4 months ago on ask ubuntu site. and answered there. And it looks like you just copied the question from there and posted it here. Was the answer received there wrong?
Also would suggest you look at the Mount man pages by executing This command in a terminal.
Code:
man mount
