Denis Mekhanikov updated IGNITE-6474:
-------------------------------------
Summary: Non-collocated IgniteSet stores duplicate values (was:
Unexpected behavior of IgniteSet in Official example running on cluster)
> Non-collocated IgniteSet stores duplicate values
> -------------------------------------------------
>
> Key: IGNITE-6474
> URL: https://issues.apache.org/jira/browse/IGNITE-6474
> Project: Ignite
> Issue Type: Bug
> Components: data structures
> Affects Versions: 2.1
> Environment: a ignite cluster with 2 nodes
> Reporter: DL Ren
>
> Here is the problem description in
> [stackoverflow|https://stackoverflow.com/questions/46343833/unexpected-behavior-of-igniteset-in-official-example]
> I tried to run org.apache.ignite.examples.datastructures.IgniteSetExample on
> cluster(2 nodes) after adding some my debug code. Some of its source code
> like following:
> CollectionConfiguration setCfg = new CollectionConfiguration();
> setCfg.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);
> setCfg.setCacheMode(CacheMode.PARTITIONED);
> // Initialize new set.
> IgniteSet<String> set = ignite.set(setName, setCfg);
> System.out.println("Set size before initializing: " + set.size()); //added by
> myslef
> // Initialize set items.
> for (int i = 0; i < 10; i++){
> set.add(Integer.toString(i));
> System.out.println("Set: " + Arrays.toString(set.toArray())); //added by
> myslef
> }
> System.out.println("Set size after initializing: " + set.size());
> In my opinion, the size of ignite set should be 10 after adding data but I
> got a number which is great than 10 and typically 15. I found that there was
> some reduplicate numbers been added to the set. The log is here:

> recommended configuration of "collocated" attribute. So what's wrong here?
