Work Description: mukund-thakur opened a new pull request, #4476:
URL: https://github.com/apache/hadoop/pull/4476
### Description of PR
Add support for multiple ranged vectored read api in PositionedReadable. The
default iterates through the ranges to read each synchronously, but the intent
is that FSDataInputStream subclasses can make more efficient readers especially
object stores implementation.
### How was this patch tested?
Added new tests. Ran older test suites in ap-south-1. All good.
### For code changes:
- [ ] Does the title or this PR starts with the corresponding JIRA issue id
(e.g. 'HADOOP-17799. Your PR title ...')?
- [ ] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies
licensed in a way that is compatible for inclusion under [ASF
2.0](http://www.apache.org/legal/resolved.html#category-a)?
- [ ] If applicable, have you updated the `LICENSE`, `LICENSE-binary`,
`NOTICE-binary` files?
