Could we have a simple test for this inheritance? Otherwise, looks fine from a cursory look.

…tionSuite.Cancellation APIs in SparkSession are isolated` ### What changes were proposed in this pull request? This PR aims to reenable `SparkSessionJobTaggingAndCancellationSuite.Cancellation APIs in SparkSession are isolated`. #48736 disabled this test because of it was flaky. In this test, futures ran on threads managed by `ForkJoinPool`. Each future invokes `SparkSession#addTag` and `SparkSession#getTag`, and tags are implemented using `InheritableThreadLocal`. So the root cause of this issue is same as #52417. But #48906 replaced `ForkJoinPool` with `Executors.newFixedThreadPool(3)` so I believe this issue no longer occurs. In fact, this issue can be reproduced by replacing `Executors.newFixedThreadPool(3)` with `new ForkJoinPool(3)` and inserting a sleep like as follows. ``` // global ExecutionContext has only 2 threads in Apache Spark CI // create own thread pool for four Futures used in this test - val threadPool = Executors.newFixedThreadPool(3) + val threadPool = new ForkJoinPool(3) ... + Thread.sleep(1000) val jobB = Future { sessionB = globalSession.cloneSession() import globalSession.implicits._ ``` Then, run the test as follows. ``` $ build/sbt 'sql/testOnly

So, we can now reenable this test. ### Why are the changes needed? For better test coverage. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? The test always passes on my dev environment even if inserting sleep like explained above. ### Was this patch authored or co-authored using generative AI tooling? No. Closes #52704 from sarutak/SPARK-50205. Authored-by: Kousuke Saruta <[email protected]> Signed-off-by: Dongjoon Hyun <[email protected]>

So, we can now reenable this test. ### Why are the changes needed? For better test coverage. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? The test always passes on my dev environment even if inserting sleep like explained above. ### Was this patch authored or co-authored using generative AI tooling? No. Closes apache#52704 from sarutak/SPARK-50205. Authored-by: Kousuke Saruta <[email protected]> Signed-off-by: Dongjoon Hyun <[email protected]>

What changes were proposed in this pull request?
This PR changes the implementation of user-provided tags to be thread-local, so that tags added by two threads to the same SparkSession do not interfere with each other.
Overlaps (from the
SparkContextperspective) are avoided by introducing a thread-local random UUID which is attached to all tags in the same thread.Why are the changes needed?
To make tags isolated per thread.
Does this PR introduce any user-facing change?
Yes, user-provided tags are now isolated on the session level.
How was this patch tested?
Local test.
Was this patch authored or co-authored using generative AI tooling?
No.
