[jira] [Commented] (IGNITE-11724) IgniteSpark integration forget to
close the IgniteContext and stops the client node in case if error during
PairFunction logic
[ https://issues.apache.org/jira/browse/IGNITE-11724?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16954588#comment-16954588 ]

------------------------------------------
Hello [~aealeksandrov], [~zaleslaw]
I don't understand what the issue here.
Ignite instance close on {{IgniteContext#close}}.
Why do you think we should close it on the exception in {{savePairs}}?

> Project: Ignite
> Issue Type: Bug
> Components: spark
> Affects Versions: 2.8
> Reporter: Andrey Aleksandrov
> Assignee: Alexey Zinoviev
> Priority: Major
> Labels: await
> Fix For: 2.8

> Time Spent: 20m
> Remaining Estimate: 0h

> Next code could hang in case if PairFunction logic will throw the exception:
> {code:java}
> JavaPairRDD<Key, Value> rdd_records = records.mapToPair(new MapFunction());
> JavaIgniteContext<Key, Value> igniteContext = new JavaIgniteContext<>(sparkCtx, configUrl);
> JavaIgniteRDD<Key, Value> igniteRdd = igniteContext.<Key, Value>fromCache(cacheName);
> igniteRdd.savePairs(rdd_records);
> Looks like next internal code (saveValues method)should also close the IgniteContext in case of an unexpected exception, not only data streamer:
> try {
> it.foreach(value ⇒
> { val key = affinityKeyFunc(value, node.orNull) streamer.addData(key, value) }
> )
> }
> finally
> { streamer.close() }
> })
> }
> {code}
