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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
