We are using Impala 2.12 along with cdh 5.16.x. We planning to upgrade to Impala 3.1.0. So will there be a need to upgrade to cdh 6.1.0 or higher inorder use Impala 3.1.0 or this can be handled using cdh 5.16.x.
yes you have to upgrade to cdh6.1.0 or higher to use impala-3.1.0 - Its not possible to selectively upgrade impala alone
