Review Comment:
There are no regression tests for the multi-child failure paths. Please add
tests for partial layout coverage in a read-ahead window, one child failing
while siblings are in flight, and eviction freeing the shared index exactly
once. The @Order(Integer.MAX_VALUE) workaround suggests shared-state leakage
between tests, so please fix the leak.
> ABFS: Enable data locality aware reads for Azure Blob Storage
> -------------------------------------------------------------

> Key: HADOOP-19946
> URL: https://issues.apache.org/jira/browse/HADOOP-19946
> Project: Hadoop Common
> Issue Type: New Feature
> Components: fs/azure
> Reporter: Manish Bhatt
> Assignee: Manish Bhatt
> Priority: Major
> Labels: pull-request-available
>
> Introduce data locality support in ABFS to improve read performance for Azure
> Blob Storage by routing read requests to the endpoint that hosts the required
> data range. The goal is to reduce latency, improve throughput, and make read
> operations more efficient for large files and distributed workloads. This
> work adds blob layout discovery, range-to-endpoint mapping, locality-aware
> range selection, and caching of layout metadata to avoid repeated lookups. It
> also enables segmented read-ahead aligned with locality boundaries and adds
> safeguards for concurrency, eviction, timeout handling, and failure
> propagation needed for reliable production-scale reads.
