---------------------------------------
Summary: RobinHoodBackwardShiftHashMap works incorrectly on big
endian architectures
Key: IGNITE-12238
URL: https://issues.apache.org/jira/browse/IGNITE-12238
Project: Ignite
Issue Type: Bug
Reporter: Andrey N. Gura
Assignee: Andrey N. Gura
Fix For: 2.8
{{RobinHoodBackwardShiftHashMap}} has bug that can be reproduced only on big
endinan architectures. In order to reproduce the problem run the following
tests:
* {{RobinHoodBackwardShiftHashMapTest.testCollisionOnRemove}}
* {{testRandomOpsPutRemove}}
The problem is {{setIdealBucket()}} method writes {{long}} value to the offheap
memory, while {{getIdealBucket()}} reads {{int}} value. For little endian
architectures it works because meaningful 4 bytes will written first to the
memory and leading zero bytes will be rewriteen by the next operation. On big
endian architecture always 4 zero bytes will be written to the memory.
