Is it possible to install Impala as it is there in CCA 175 syllabus. I am aware of Hortonworks Platform encourages Tez instead of Cloudera Impala but still it is possible to install Impala even in HDP.
As Impala is Apache Project I don’t see any reason for not to work on HDP. I found official documentation from MapR and AWS for Impala Configuration in their stack.
The following steps may work by taking the help from Hortonworks.
