HA问题

[Bruce2jiang]

我两个canal server 都设置了这个：canal.instance.global.spring.xml = classpath:spring/default-instance.xml

，但查看zookeeper 这个instance ：canalcrm，没有running信息 [zk: localhost:2181(CONNECTED) 20] ls /otter/canal/destinations/canalcrm/running []

[Bruce2jiang]

如果我查看/otter/canal/destinations/canalcrm/cluster，两个server信息都有，但是每个server下面又没数据，看不出来哪个server是主节点 [zk: localhost:2181(CONNECTED) 23] ls /otter/canal/destinations/canalcrm/cluster [10.125.210.15:11111, 10.125.210.14:11111]

[zk: localhost:2181(CONNECTED) 24] ls /otter/canal/destinations/canalcrm/cluster/10.125.210.15:11111 []

[zk: localhost:2181(CONNECTED) 25] ls /otter/canal/destinations/canalcrm/cluster/10.125.210.14:11111 []

谁能解答一下

[Fanduzi]

用get get /otter/canal/destinations/mgr_zyx_2/running

[Bruce2jiang]

没用，能不能找个懂得回到一下

[Fanduzi]

得. 咱不懂撤了😆

这个问题解决了吗？ @Bruce2jiang 目前我遇到一个问题，可能跟你的很相似。 现象： 两个Canal节点配置HA，写Kafka。消费位点meta文件，保存在本地。当主节点挂了，备节点上的meta文件并没有同步主节点的消费信息。 不知道是我配置有问题，还是存在什么异常？
