Description

As said in summary, Is there anyway to do data migtation from kylin 2.6.2 to the same version across different cluster?

 

I have tried the CubeMigrationCrossClusterCLI by putting the CubeMigrationCrossClusterCLI  jar file under the path $KYLIN_HOME/tool in the source cluster.

 

The CubeMigrationCrossClusterCLI  jar file is got from kylin 3.1.0 version.

 

But, I got erros like this:

java.net.ConnectException: Connection refused (Connection refused)

 

The commad I use is this:

$KYLIN_HOME/bin/kylin.sh org.apache.kylin.tool.migration.CubeMigrationCrossClusterCLI -kylinUriSrc ADMIN:KYLIN@srcHost:17070 -kylinUriDst ADMIN:KYLIN@destHost:17777 -all -execute true -schemaOnly false -overwrite true

 

Can it work? If not, is there any other way?

 

Thanks for help!
