Impala Changes between CDH and CDP
There are some differences between Impala in CDH and Impala in CDP. These changes affect Impala after you migrate your workload from CDH 5.13-5.16 or CDH 6.1 or later to CDP Private Cloud Base or Public Cloud. Some of these differences require you to change your Impala scripts or workflow.
The version of Impala you used in CDH version 5.11 - 5.16 or 6.1 or later changes to Impala 3.4 when you migrate the workload to CDP Private Cloud Base or Public Cloud.
