Robert Levas updated HADOOP-16340:
----------------------------------
Summary: ABFS driver continues to retry on IOException responses from REST operations (was: ABFS driver continues to retry on access denied responses from REST operations)
> ABFS driver continues to retry on IOException responses from REST operations
> ----------------------------------------------------------------------------
>
> Key: HADOOP-16340
> URL: https://issues.apache.org/jira/browse/HADOOP-16340
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/azure
> Affects Versions: 3.3.0
> Reporter: Robert Levas
> Priority: Major
>
> ABFS driver continues to retry (until retry count is exhausted) upon access denied responses from REST operations.
> In the exception hander for IOExceptions at [https://github.com/apache/hadoop/blob/65f60e56b082faf92e1cd3daee2569d8fc669c67/hadoop-tools/hadoop-azure/src/main/java/org/apache/hadoop/fs/azurebfs/services/AbfsRestOperation.java#L174-L197], there is no way exit out of the retry loop by re-throwing an exception unless one of the following conditions have been met:
> * The retry limit was hit
> * An HttpException was encountered
> From an {{org.apache.hadoop.fs.azurebfs.extensions.CustomTokenProviderAdaptee}} or {{org.apache.hadoop.fs.azurebfs.extensions.CustomDelegationTokenManager}} implementation, there is no way to create an {{org.apache.hadoop.fs.azurebfs.oauth2.AzureADAuthenticator.HttpException}} since the constructor is package private.
> Either the exception handler needs to generic handle exceptions like {{java.nio.file.AccessDeniedException}} and {{java.io.FileNotFoundException}}, or the access to {{org.apache.hadoop.fs.azurebfs.oauth2.AzureADAuthenticator.HttpException}} needs to be set to that custom implementations can use it.
