Overview

• This release addressed several internal code compatibility issues. To upgrade a cluster from V4.2.2_CE or V4.2.2_CE_HF1 to a version higher than V4.2.2_CE_BP1, you need to upgrade it to V4.2.2_CE_BP1 first.

Bug fixes

• Fixed the issue where during the current execution of transfer, medium compaction, and backup, if an exception occurs, such as OSS write failure, Error 4016 might be reported during physical restore.
• Fixed the issue that could cause core dump on OBServer nodes when creating and switching sessions frequently.
• Fixed the issue that could cause core dump on OBServer nodes due to memory allocation problems in parallel column deletion scenarios.

发版目的

• 修复若干内部代码兼容性问题，已经部署 V4.2.2_CE 或 V4.2.2_CE_HF1 版本的集群，升级更高版本时，需经停 V4.2.2_CE_BP1 版本。

缺陷修复

• 修复在 Transfer、Medium Compaction 和备份操作并发执行期间，遇到写入 OSS 失败等可重试错误的异常场景时，可能会导致物理恢复数据报错 4016 的问题。
• 修复多次创建并切换 Session 时，可能导致 OBServer Core 的问题。
• 修复在并行删除列场景下，可能由于内存分配问题导致 OBServer Core 的问题。
