HBase区域OFFLINE且无法分配：无效主机名致日志拆分失败求助

为配置HBase多网卡，我们将hbase.regionserver.ipc.address和hbase.master.ipc.address设置为0.0.0.0，触发了早年已发现的主机名解析问题。恢复配置后，有70个区域处于OFFLINE状态，仍绑定到主机名为0:0:0:0:0:0:0:0的Dead Region Server。

重启Master本应转换区域状态，但因主机名无效，处理M_SERVER_SHUTDOWN事件时尝试拆分日志失败，报错信息如下：

2024-04-24 11:02:26,475 ERROR [MASTER_SERVER_OPERATIONS-master:60000-1] executor.EventHandler: Caught throwable while processing event M_SERVER_SHUTDOWN

经测试，Hadoop不认可包含该无效主机名的文件名：
执行以下命令：

/home/gs/Dev/hadoop/bin/hdfs dfs -mkdir /hbase/WALs_mike/0:0:0:0:0:0:0:0,60020,1713708572030-splitting

返回错误：/hbase/WALs_mike/0:0:0:0:0:0:0:0,60020,1713708572030-splitting is not a valid DFS filename

我们使用的HBase版本为0.96.1.1，核心问题是代码无法处理无效主机名0:0:0:0:0:0:0:0。现寻求解决以下两个问题：

• 如何禁用M_SERVER_SHUTDOWN事件处理时的日志拆分？
• 如何修改这些区域关联的主机名？

已尝试使用hbck及HBase Shell的assign、move、unassign命令，均未生效，报错信息如下：
