baimu7 opened a new issue, #12318:
URL: https://github.com/apache/ignite/issues/12318
I implemented an AffinityFunction interface class called
AvgAffinityFunction. However, when the client configures and creates a cache
using the AvgAffinityFunction class, the server reports an error saying that
the AvgAffinityFunction class is not found. I tried deploying the
AvgAffinityFunction class on the server using the three methods mentioned in
the documentation, but all attempts failed. Could you suggest where my
configuration might be incorrect? I am using JDK 8 and Ignite version 2.15.
Below are the three deployment methods I tried and the corresponding errors:
1. Peer Class Loading
Server-side configuration:
`<bean id="grid.cfg"
class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="peerClassLoadingEnabled" value="true"/>
<property name="deploymentMode" value="CONTINUOUS"/>
</bean>`
Despite enabling peer class loading, the server still reports a class not
found error.
2. Local Directory and URL Deployment
I attempted local directory and URL deployment with the following
configuration:
`<bean id="grid.cfg"
class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="peerClassLoadingEnabled" value="true"/>
<property name="deploymentMode" value="CONTINUOUS"/>
<property name="deploymentSpi">
<bean class="org.apache.ignite.spi.deployment.uri.UriDeploymentSpi">
<property name="temporaryDirectoryPath"
value="/tmp/temp_ignite_libs"/>
<property name="uriList">
<list>
<value>file://freq=2000@/Users/name/deploy</value>
</list>
</property>
</bean>
</property>
</bean>`
Error:
