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.

SSH into the host system as a root user.
Run the following command to set write access permission to the /tmp directory:
```
chmod 1777 /tmp
```
Verify the permission of the /tmp directory by running the list command as follows:
```
ls -la
```
The permissions of the /tmp directory should show drwxrwxrwt.

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

Repeat this task on every host in your cluster.
