似乎找到问题在哪里了，尝试把这个参数改下试试？
meta_client_retry_times ，设置为0, 只修改所有的graphd-conf就可以。
这个的话，如果有leaderChange的part，仍然导致创建失败，但是应该避免创建多次的问题。
我之前修改过时区，有影响吗
不执行balance leader也会导致leaderchange吗，什么情况下会导致leaderchange呢？
不太确定是否对这个问题有影响，但肯定对集群有影响，在修改节点时区的过程中，可能导致节点间时间相关的操作就不同步了
这个多次snapshot的创建时间上有疑问，不清楚为什么第一次成功了，还要retry。
如果数据正在写入的时候执行create snapshot会失败吗？
会block所有的write
把数据都删除了，重新部署了下，数据量少的时候还能正常，数据多的时候就又有问题了，执行了一次失败了，报超时：
(root@nebula) [(none)]> create snapshot
[ERROR (-8)]: RPC failure in MetaClient: N6apache6thrift9transport19TTransportExceptionE: Timed Out
数据量大，这个超时时间是不是可以配置呢？
过一会显示成功，这个快照是否可用呢？
如果这个问题解决不了，是否能够通过直接备份data_path下面的数据来实现快照功能呢？
meta_client_timeout_ms 这个参数可以控制超时。
另外，其实snapshot就是对data做了一个hard link，跟直接备份data目录是一样的，如果是手动备份，尽量要block write。
如果snapshot的状态是VALID，说明这个snapshot已经创建成功了。当所有步骤都成功后，最后才将snapshot的状态修改为VALID.
这么说来，之前的多次创建snapshot的原因也比较清晰了。每次创建snapshot的时候，并不是创建失败，而是graph和meta的连接timeout了，但是meta任然在继续工作，直到创建完成。这个过程中graph因为收到了timeout消息，graph由metaClient再次进行了重试。导致创建了多次，且大多数都是能创建成功的。
这个检查逻辑本身存在问题，我们后续会分析并完善一下。谢谢您的反馈。

meta_client_timeout_ms这个参数是配置在graphd-conf还是meta-conf里面的？
Graph.conf就可以
现在创建snapshot没问题了，还有个问题咨询下：
现在集群是3台meta，通过java版本的client来链接meta。
使用MetaClientImpl这个类，传入3个meta的ip。发送在调用connect的时候会概率性报错：
ERROR [main] - List Spaces Error Code: -11
这个是不是因为在3个ip中只有一个是leader，而通过client只能链接leader，链接其他的就会报错？
这个是正常的吗？还是集群有问题？
正常的 必须连leader
