Resolution: Duplicate
If you don't mind, this is too logically related to SPARK-11139 to make
separate JIRAs.
> Make StreamingContext.stop() exception-safe
> -------------------------------------------
>
> Key: SPARK-11137
> URL: https://issues.apache.org/jira/browse/SPARK-11137
> Project: Spark
> Issue Type: Bug
> Components: Streaming
> Affects Versions: 1.5.1
> Reporter: Felix Cheung
> Priority: Minor
>
> In StreamingContext.stop(), when an exception is thrown the rest of the
> stop/cleanup action is aborted.
> Discussed in https://github.com/apache/spark/pull/9116,
> srowen commented
> Hm, this is getting unwieldy. There are several nested try blocks here. The
> same argument goes for many of these methods -- if one fails should they not
> continue trying? A more tidy solution would be to execute a series of () ->
> Unit code blocks that perform some cleanup and make sure that they each fire
> in succession, regardless of the others. The final one to remove the shutdown
> hook could occur outside synchronization.
> I realize we're expanding the scope of the change here, but is it maybe
> worthwhile to go all the way here?
> Really, something similar could be done for SparkContext and there's an
> existing JIRA for it somewhere.
> At least, I'd prefer to either narrowly fix the deadlock here, or fix all of
> the finally-related issue separately and all at once.
