Upgrading Impala
Upgrading Impala from an older to a newer version is similar to other application up-
grades on Linux machines. Upgrading Impala requires stopping the currently running
Impala services. Upgrade Impala, and then add extra configurations if needed, and fi-
nally restart Impala services. Here we will learn how we can upgrade Impala services
depending on our initial installation method.
