> ABFS: GetPathStatus Optimization on OpenFileForRead

> Key: HADOOP-19795
> URL: https://issues.apache.org/jira/browse/HADOOP-19795
> Project: Hadoop Common
> Issue Type: Task
> Components: fs/azure
> Affects Versions: 3.4.1, 3.4.2
> Reporter: Manika Joshi
> Assignee: Manika Joshi
> Priority: Major

>
> We do a getPathStatus call during file open for read. This call is primarily
> used to fetch the file’s metadata properties before the actual read begins.
> We are now introducing an optional, config-driven read flow that avoids the
> getPathStatus call during open and instead derives required metadata from the
> read response itself.
