Dushyanth commented on HADOOP-12535:
------------------------------------
[~madhuch-ms] This is a known deviation for append support in WASB. Append
expects the application to enforce single modifier semantics for a file. Unlike
HDFS where we have lease or lock on the path, WASB does not have the same
semantics and we expect the applications to enforce that the file is not
modified (rename or delete) during append.
I think we can skip this test for Append at this time and re-enable it when we
bring append support to have the same semantics as HDFS.

> This issue proposes to implement the Hadoop {{FileSystem}} contract tests for
> hadoop-azure/WASB. The contract tests define the expected semantics of the
> {{FileSystem}}, so running these for hadoop-azure is likely to catch
> potential problems and improve overall quality.
