Question

I use ansible install ignite, just replace artiface zip. The error log for the startup script is as follows, it's strange ClassNotFoundException:ZkDiscoveryNodeFailEventData( which occur in 2.7 version).

I have solved this problem , just change zkRootPath from /apacheIgnite to /otherPath, or connect zookeeper shell and rmr /apacheIgnite
<property name="discoverySpi">
<bean class="org.apache.ignite.spi.discovery.zk.ZookeeperDiscoverySpi">
<property name="zkConnectionString" value="ip1:2181,ip2:2181,ip3:2181"/>
<property name="zkRootPath" value="/apacheIgnite"/>
<property name="sessionTimeout" value="400000"/>
</bean>
</property>
besides, you need to delete the data for the paths in the following properties
<property name="storagePath" value="/xxx/persistent" />
<property name="walPath" value="/xxx/wal_store"/>
<property name="walArchivePath" value="/xxx/wal_archive"/>
