Sergey Kosarev updated IGNITE-11909:
------------------------------------
Affects Version/s: 2.7
> Cache.invokeAll() returns a map with BinaryObjects as keys
> ----------------------------------------------------------
>
> Key: IGNITE-11909
> URL: https://issues.apache.org/jira/browse/IGNITE-11909
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.7
> Reporter: Sergey Kosarev
> Priority: Major
> Labels: APIBug
>
> Preconditions:
> 1) AtomicityMode.Transactional
> 2) Key is custom object. (i.e MyKey)
> cache.returnAll returns should return Map<MyKey, EntryProcessorResult<T>>,
> but keys
> processed on remote node(s) return not unwrapped (as BinaryObject), so we can
> get a map with mixed keys:
> {code}
> key.class = BinaryObjectImpl, key =
> org.apache.ignite.examples.datagrid.CacheEntryProcessorExample2$MyKey
> [idHash=151593342, hash=31459296, i=2]
> key.class = MyKey, key = MyKey{i=7}
> key.class = BinaryObjectImpl, key =
> org.apache.ignite.examples.datagrid.CacheEntryProcessorExample2$MyKey
> [idHash=405215542, hash=31638042, i=8]
> key.class = MyKey, key = MyKey{i=1}
> key.class = BinaryObjectImpl, key =
> org.apache.ignite.examples.datagrid.CacheEntryProcessorExample2$MyKey
> [idHash=1617838096, hash=31548669, i=5]
> key.class = MyKey, key = MyKey{i=0}
> key.class = BinaryObjectImpl, key =
> org.apache.ignite.examples.datagrid.CacheEntryProcessorExample2$MyKey
> [idHash=138776324, hash=31578460, i=6]
> key.class = MyKey, key = MyKey{i=9}
> key.class = MyKey, key = MyKey{i=4}
> {code}
> Reproducer :
> {code}
> public class CacheEntryProcessorExample2 {
> /** Cache name. */
> private static final String CACHE_NAME =
> CacheEntryProcessorExample2.class.getSimpleName();
> /** Number of keys. */
> private static final int KEY_CNT = 10;
> /** Set of predefined keys. */
> private static final Set<MyKey> KEYS_SET;
> /**
> * Initializes keys set that is used in bulked operations in the example.
> */
> static {
> KEYS_SET = new HashSet<>();
> for (int i = 0; i < KEY_CNT; i++)
> KEYS_SET.add(new MyKey(i));
> }
> /**
> * Executes example.
> *
> * @param args Command line arguments, none required.
> * @throws IgniteException If example execution failed.
