Upgrading Drill

This section describes how to upgrade Drill without the Installer.

Before you upgrade Drill, complete the pre-upgrade steps.

Attention: Due to Drill version changes (3-digit to 4-digit), you cannot upgrade from Drill in MEP 7.0.0 (Drill 1.16.1) to Drill in MEP 7.0.1 (Drill 1.16.1.5) or later. You must perform a new installation of Drill. Alternatively, if you are running Drill on CentOS or RHEL, you can issue the following command as a workaround to upgrade Drill:

rpm -Uv --<old-package> <path/to/packages>/*.rpm

Complete the following steps on the Drill server and client nodes as root or using sudo to upgrade Drill without the Installer:

To eliminate cached packages and files, issue the following command:
```
yum clean all
```
To upgrade Drill, issue the command appropriate for your system on each Drill node:
- RedHat/CentOS
```
yum update mapr-drill
```
- Ubuntu
```
sudo apt-get install mapr-drill
```
- SUSE
```
zypper update mapr-drill
```
  Note: SUSE is supported as of Drill 1.9.0-1703 and Drill 1.10.0-1703.
