Is there any risk to delete old HDP directories?

[#1]

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

...

Thanks Jonas!

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