Raul da Silva Martins updated HADOOP-13475:
-------------------------------------------
Release Note: (was: The Azure Blob Storage file system (WASB) now
includes optional support for use of the append API by a single writer on a
path. Please note that the implementation differs from the semantics of HDFS
append. HDFS append internally guarantees that only a single writer may append
to a path at a given time. WASB does not enforce this guarantee internally.
Instead, the application must enforce access by a single writer, such as by
running single-threaded or relying on some external locking mechanism to
coordinate concurrent processes. Refer to the Azure Blob Storage documentation
page for more details on enabling append in configuration.)
