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
(having the 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
directory.
Your /tmp directory is now writable on your cluster hosts.
