RONIERI MARQUES RAMALHO commented on DRILL-7512:
------------------------------------------------
Don't know if it helps but, I have a very similar problem using just Azure apps
(ADF and Azcopy) to read from Azure Data Lake Storage Gen 2. So I don't think
Apache Drill is the one to blame
I opened a case on Microsoft, and I'm waiting for a response, until now we
believe there's something corrupted on the data files.
The workarround was, to read those files using Databricks pyspark dataframes,
and then rewriting data on the Data Lake again
But as this "corruption" happened twice in a 4 months interval, I'll wait for
the investigation to find the cause, in hopes to avoid it

> I can use a DFS plugin to read and write parquet locally but not with Gen 2.
> ADLS Gen 1 works fine for reading and writing.
> I have tried two version of Drill and also the recommended jar files as well
> as older versions and still no luck.
> Does Drill support data lake gen 2 with parquet files.
