      Description

      When all Yarn containers are busy a new Hive CLI session with Tez set as the execution engine won't start as it attempts to allocate a container for the AM.

      The request is to launch an AM only when needed.

      Analysts log into hive using CLI, write queries , check the schema analyze explain etc.. then launch a query, with the current model they are blocked from doing if the queue is full or if all containers are busy.
