My views are created out of parquet files stored in mapr fs. For some of the views, while accesing through DREMIO, it gives error like “Error while expanding view…” which on checking JOB Profile indicates , the error is caused by ‘(java.security.AccessControlException) Permission Denied’.
And sometimes, it gives error “Access denied reading dataset Findatalake.mnr.cts.”
Some of the error gets resolved on refreshing the metadata but sometimes it does not.
I want to know is it always actually related to permission and access. How do I check the metadata, if is it corrupted and for what reasons does it get corrupted.
View Corrupt – How can we find if a view is corrupt
Will view be corrupt if a new column is added at the end of the current file. Will this ever happen as we always do this via a schema.
What happens if the schema changes|
Will the file read fail if a new column is added at the end of the file.|
Do we need to recreate views / if yes, when?
