Upgrading Impala without Cloudera Manager
The steps to be followed are as follows:
1. Stop Impala services and Impala-state-store in all nodes where it is installed.
2. Validate if any update-specific configuration is needed and, if so, please ap-
ply that configuration.
3. Update the Impala-server and Impala shell using appropriate update com-
mands on your Linux OS. Depending on your Linux OS and Impala package
types, you might be using these commands, for example, "yum" on RedHat/
CentOS Linux and "apt-get" on the Ubuntu/Debian Linux OS.
4. Restart Impala services.
