Subject [jira] [Comment Edited] (HUDI-539) No FileSystem for scheme: abfss

----------------------------------------------------------

I have ABFS supported in my version of hadoop.

If I execute 

{{path.getFileSystem(spark.sparkContext.HaddopConfiguration); }}

it will correctly get the file system. 

 

The problem is the HUDI code executes 

{{path.getFileSystem(new Configuration());}}

and passes in a blank hadoop configuration.

> Hi,
>  I'm trying to use hudi to write to one of the Azure storage container file systems,
ADLS Gen 2 (abfs://). ABFS:// is one of the whitelisted file schemes. The issue I'm facing
is that in {{HoodieROTablePathFilter}} it tries to get a file path passing in a blank hadoop
configuration. This manifests as {{java.io.IOException: No FileSystem for scheme: abfss}}
because it doesn't have any of the configuration in the environment.
