> ABFS: [FnsOverBlob][Optimizations] Reduce Network Calls In Create and Mkdir
> Flow
> --------------------------------------------------------------------------------
>
> Key: HADOOP-19448
> URL: https://issues.apache.org/jira/browse/HADOOP-19448
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.4.2
> Reporter: Anuj Modi
> Assignee: Anmol Asrani
> Priority: Major
> Labels: pull-request-available
>
> Implementing Create and Mkdir file system APIs for FNS(HNS Disabled) accounts
> on Blob Endpoint involves a lot of checks and marker file creations to handle
> implicit explicit cases of paths involved in these APIs.
> This Jira proposes a few optimizations to reduce the network calls wherever
> possible and in case where create/mkdir is bound to fail, it should fail
> faster before doing any post checks,
