Using pdi9.1.0.0-324 in java

Quote:

I used pdi in a project, the version is 9.1.0.0-324.
I encountered a problem when generating ktr files. The specific error is:

 2024/06/14 15:46:19 - org.pentaho.big.data.impl.cluster.NamedClusterManager@53305564 - ERROR (version Unknown, build 0 from 2024/06/14 15:46:18.580 by zyl) : No metastore found and exception encountered looking for user-specified or legacy metastore

how should I deal with it?
