Hello,

as the title already suggests, i'm not able to remove a file via the shell (%sh rm -f "path") nor continue the notebook 6.2 onwards on (6.3 etc...) inside DataBricks. I'm using the DataBricks Community edition.

While the error message is clear:

"Error in SQL statement: AnalysisException: Can not create the managed table('`default`.`DeviceData`'). The associated location('dbfs:/user/hive/warehouse/devicedata') already exists.",

I am not able to figure out how to resolve this. Skipping to the next cells will yield:

"Error in SQL statement: AnalysisException: Table or view not found for 'DESCRIBE TABLE': DeviceData; line 1 pos 0"

i tried removing it via the shell but it has no effect. I tried restart and clearing all clusters - no effect. I'm not familiar with the Classroom setup, so i could not find a solution there either. Also the table doesn't show up under "Data" via the Databricksexplorer.

Thank you in advance.

Best regards
