问题
I'm using the 14 day Premium free trial. I'm trying to create and run a cluster in databricks (I'm following the quick start guide). How ever I'm getting the following error "Operation results in exceeding quota limits of Core. Maximum allowed: 4, Current in use: 4, Additional requested: 4." I cant bump up the limit because I am in the free trial. I'm trying to run only 1 worker on the weakest worker type. I've already tried deleting all my subscriptions and made sure that there are no other clusters being used.
Edit: Im thinking it might be because the worker and the driver each use 4 cores. Is there a way to use databricks in the free trial?
回答1:
I think these are your options:
- log a support request to ask for more quota (apparently not a thing for free\trial subs)
- use different VM types for master and slave (like Standard A2 for master and Standard D2 for slave) because they share different core limits
- Use smaller nodes (which I think you've mentioned is not possible), but it might be possibly just not with the portal

Azure free trial is eligible to VM with total 4 vCPUs.
Note: Free Trial subscriptions are not eligible for limit or quota increases.
If you have a Free Trial subscription, you can upgrade to a Pay-As-You-Go subscription.
Upgrade Azure Free Trial to Pay-As-You-Go
For more details, refer "Azure subscription and service limits, quotas, and constraints".
