Subject [jira] [Commented] (HADOOP-14450) ADLS Python client inconsistent when used in tandem with AdlFileSystem
Date Tue, 23 May 2017 20:38:04 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16021792#comment-16021792

Mingliang Liu commented on HADOOP-14450:

I'd suggest a simple unit test to reproduce the bug (if any), or commands in FSShell. Ad hoc
pythons clients wrapping ADLFileSystem may have it's own bug.

> Impala uses the AdlFileSystem connector to talk to ADLS. As a part of the Impala tests,
we drop tables and verify that the files belonging to that table have been dropped for all
filesystems that Impala supports. These tests however, fail with ADLS.
> If I use the Hadoop ADLS connector to delete a file, and then list the parent directory
of that file using the above Python client within the second, the client still says that the
file is available in ADLS.
> This is the Python client from Microsoft that we're using in our testing:
> https://github.com/Azure/azure-data-lake-store-python
> Their release notes say that it's still a "pre-release preview":
> https://github.com/Azure/azure-data-lake-store-python/releases
> Questions for the ADLS folks:
> Is this a known issue? If so, will it be fixed soon?
> Or is this expected behavior?
> I'm able to deterministically reproduce it in my tests, with Impala on ADLS.
