> Consider the following directory structure
> dir/col=X/some-files
> If we create a text format streaming dataframe on {dir/col=X/}, then it should not consider as partitioning in columns. Even though the streaming dataframe does not do so, the generated batch dataframes pick up col as a partitioning columns, causing mismatch streaming source schema and generated df schema. This leads to runtime failure:
> 18:55:11.262 ERROR org.apache.spark.sql.execution.streaming.StreamExecution: Query query-0 terminated with error
> java.lang.AssertionError: assertion failed: Invalid batch: c#2 != c#7,type#8
