原因分析

客户使用的JDK中的jar包与MRS服务认证的jar包版本不一致。

处理步骤

1. 以root登录集群Master1节点。
2. 执行如下命令，查看MRS服务认证的jar包。

   ll /opt/share/local_policy/local_policy.jar

   ll /opt/Bigdata/jdk{version}/jre/lib/security/local_policy.jar

3. 将步骤2中的jar包下载到本地。
4. 将下载的jar包替换到本地JDK目录/opt/Bigdata/jdk/jre/lib/security。
5. 执行cd /opt/client/HBase/hbase/bin命令，进入到HBase的bin目录。
6. 执行sh start-hbase.sh命令，重启HBase组件。
