Thanks for reply,
I had done clean build with maven few times. But always report
/Users/xxx/Code/spark/core/target/generated-sources/org/apache/spark/status/protobuf/StoreTypes.java:658:9
java: symbol not found
Symbol: class UnusedPrivateParameter
Location: class org.apache.spark.status.protobuf.StoreTypes.JobData
I think maybe it's protobuf version conflict?
