Hi, '-kylinUriSrc ADMIN:KYLIN@srcHost:17070' will fetch configuration from source cluster by HTTP request.
‘Connection refused’ is likely due to Kylin Server is not running in ’srcHost’ or the listening port is not 17070 (7070 by default). If you checked both process and port is fine. Try two alternatives: 1. Try an offline way: use 'metastore.sh backup' to export source cluster’s metadata to a directory, and set -kylinUriSrc to exported directory (Read exported metadata from local directory). 2. Or set -kylinUriSrc to source cluster’s properties file (Read source cluster's metadata storage directly) If you are going to try Kylin 4, read this article: https://cwiki.apache.org/confluence/display/KYLIN/How+to+migrate+metadata+to+Kylin+4 <https://cwiki.apache.org/confluence/display/KYLIN/How+to+migrate+metadata+to+Kylin+4> for reference. > 2021年4月24日 下午6:20，Aaron Duan (Jira) <[email protected]> 写道： > > -kylinUriSrc ADMIN:KYLIN@srcHost:17070
