Jing Zhao updated HDFS-10468:
-----------------------------
Attachment: HDFS-10468.002.patch
Thanks for the review, [~iwasakims]. I agree there are still many places in
DFSInputStream that have not correctly handle the interrupt. But considering
the current complexity of the DFSInputStream code, I do not plan to fix all of
them in this jira. To achieve that we may also need to do more code
refactoring. Maybe we can create an umbrella jira for this later.
I did another quick skim of the current DFSInputStream code and fixed several
other places. Uploaded 002 patch.

> If an interrupt comes in during an HDFS read - it looks like HDFS ends up
> ignoring it (handling it), and retries the read after an interval.
> An interrupt should result in the read being cancelled, with an
> InterruptedException being thrown.
> Similarly - if an HDFS op is started with the interrupt status on the thread
> set, an InterruptedException should be thrown.
