Is there any risk to delete old HDP directories?

hosako — Fri, 16 Sep 2022 09:46:47 GMT

Upgraded a cluster many times and current version is HDP 2.3.2

Would like to delete the following directories. Would it be safe to delete with rm command?

$ sudo du -hx --max-depth=1 /usr/hdp | grep G

2.8G /usr/hdp/2.3.2.0-2950

1.7G /usr/hdp/2.2.0.0-2041

2.0G /usr/hdp/2.2.6.0-2800

2.0G /usr/hdp/2.2.4.2-2

2.6G /usr/hdp/2.3.0.0-2557

...

You should not remove old packages by removing these folders via "rm -rf ....". There are many locations where HDP stores files, packages etc..

You can uninstall old versions for example via:

yum erase -y \*2_3_0_0_2557\*

Make sure you are not removing any current packages. Above command will remove the packages for the specified version, however you will still find some old log and config files (I usually keep them as a reference, but I think you can remove them without any problems).

Thanks Jonas!

Based on your advise, I'll do "yum erase `yum list | grep -P '\b2.3.0.0-2557\b' | awk '{ print $1 }'`"
