HDP 2.3 to 2.5 Rolling Upgrade MySQL Requirements

[#1]

Hi,

I am upgrading my cluster since HDP 2.1. I used there MySQL version 5.1. Now I am going to upgrade HDP 2.3 to 2.5 using Express Upgrade. During install of HDP 2.5 packages I got an error that some mysql packages require mysql-community-common and devel of version 5.7.9. There is nothing about MySQL upgrade is required in the documentation. My question is: does HDP 2.5 contains and upgrades MySQL? and which version of MySQL do I need to have before upgrade?

I am using MySQL for Ranger and Hive Metastore.

@Edgar Daeds

you're required to have MySQL 5.1 and up https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/bk_release-notes/content/ch01s02s03.html

HDP upgrade does not upgrade MySQL for you. Consider providing the error log for us to help debug your issues.

Thanks for the answer.

Actually the problem has gone, because I downgraded MySQL to version 5.7.9 (which was required) from 5.7.13. The problem was about requirements, Ambari needed mysql-community-common and devel of version 5.7.9.
