Summary: ABFS: Support FileStatus input to OpenFileWithOptions()
via OpenFileParameters
Key: HADOOP-17682
URL: https://issues.apache.org/jira/browse/HADOOP-17682
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/azure
Reporter: Sumangala Patki
Assignee: Sumangala Patki
ABFS open methods require certain information (contentLength, eTag, etc) to be
sent to Store to open the file at the given path. This information is retrieved
via a GetFileStatus request to backend, resulting in a total of two Store calls
to carry out the open function.
However, client applications may often have access to the FileStatus prior to
invoking the open API. Providing this FileStatus to the driver through the
OpenFileParameters argument of openFileWithOptions() can avoid the additional
call to Store for FileStatus.
This PR adds handling for the FileStatus instance (if any) provided via the
OpenFileParameters argument.
