Hi,

I am new to hadoop, we are having a task of upgrading hive 1.2.1 to hive 2.x, currently we are having Hdp 2.6.4 version. Is there any step by step procedure or documentation on how to perform it and what precautions needs to be taken before performing the upgrade?

Thanks,

Kam

Unfortunately, it's not advisable or recommended to upgrade individual components of HDP as this will cause inconsistencies during the subsequent version upgrade. When Upgrading form like 2.6.4 to HDP 3.x see upgrade hwx documents

You must follow the Prerequisites and there are Hive Post-upgrade Tasks and steps included. HWX delivers new versions as a complete Version major upgrade or minor versions are just corrections

Generally in cases, dependency services may be affected due to some new configuration on the latest system. It is advisable to read the release document and bugs related to new version before the upgrade.
