We have the same issue using a shared cluster running DBR 14.3:
Code executed:
dfNew = dfTmp.withColumn(HashKeyColumnName, F.sha2(F.concat_ws("||", *ColumnList), 256))
Error received:
Error in callback <bound method UserNamespaceCommandHook.post_run_cell of <dbruntime.DatasetInfo.UserNamespaceCommandHook object at 0x7fb0501caef0>> (for post_run_cell):
Issue triggering this error: dfTmp contains columns with ARRAY<> datatypes
Main issue: this error is in a try/except block which does not catch the error
Using a single user cluster is not an option
