我们有ambari集群版本2.5.0.3（有3个主节点和3个工作节点）
我们正在从hdp版本2.6.0.3升级到2.6.4版本
在最后阶段安装失败

apears在finalize upgrade pre check下的错误是

The following components were found to have version mismatches.  Finalize will not complete successfully:
master03.sys5dns.com: HDFS/ZKFC reports UNKNOWN
master01.sys5dns.com: HDFS/ZKFC reports UNKNOWN

同时：

{"hosts":["master01.sys5dns.com","master03.sys5dns.com"],"host_detail":{"master01.sys5dns.com":[{"service":"HDFS","component":"ZKFC","version":"UNKNOWN"}],"master03.sys5dns.com":[{"service":"HDFS","component":"ZKFC","version":"UNKNOWN"}]}}

我们被困在这个阶段
请告知-hdfs/zkfc报告的含义未知？
