Issue enabling mosaic

[reggie]

Hi,

I am trying to install mosaic on my cluster, but get the error once I use 'enable_mosaic': 

ImportError: cannot import name '_to_java_column' from 'pyspark.sql.functions' (/databricks/spark/python/pyspark/sql/functions/__init__.py)
File <command-1412689069782833>, line 2

      5 from mosaic.utils.types import ColumnOrName

The commands I used to import mosaic are:

%pip install databricks-mosaic

%python
from pyspark.sql.functions import *
from mosaic import enable_mosaic
enable_mosaic(spark, dbutils)

 I have already verified that I have the dependencies required using 

%python pip show databricks-mosaic

which outputs the following:

Name: databricks-mosaic
Version: 0.4.2

Requires: geopandas, h3, ipython, keplergl, pyspark
Required-by: 

My cluster configuration is as follows, with Photon enabled:

• 2-5 Workers 256-640 GB
• Memory 64-160 Cores
• 1 Driver128 GB Memory, 32 Cores
• Runtime14.3.x-scala2.12
• Unity Catalog
• Photon
• Standard_D32a_v4
• 36–72 DBU/h

I've also tried to restart my cluster to no avail.

Is there a way I can get mosaic successfully enabled to access the spatial functions?

Hi @reggie ,

You're using wrong runtime. Mosaic 0.4.x series only supports DBR 13.x DBRs. Look at below documentation and make sure that you meet with all reqeuirements:

Thank you, I thought mosaic requires a DBR at least 13.x since I didn't get a version error, but this fixed my problem 🙂

Thanks, I had the same issue and I was able to fix it
