Configuring /tmp directory for cluster hosts
You must ensure that the /tmp directory is writable so that Cloudera Manager can use the directory for installing hosts and for generating certificates and credential scripts.
By default, the /tmp directory is writable. If you have changed
the default permissions for the /tmp directory, then you must
reset the permissions so that the /tmp directory is writable
drwxrwxrwt permission). Cloudera Manager uses the
/tmp directory when you install hosts using the Cloudera
Manager server and for generating certificates and credential scripts. Cloudera
Manager’s single file installer also uses the /tmp
- SSH into the host system as a root user.
Run the following command to set write access permission to the /tmp
chmod 1777 /tmp
Verify the permission of the /tmp directory by running the list command as
ls -laThe permissions of the /tmp directory should show drwxrwxrwt.
Your /tmp directory is now writable on your cluster hosts.
