stack created HBASE-8479: ---------------------------- Summary: AggregateClient breaks bigtop compile Key: HBASE-8479 URL: https://issues.apache.org/jira/browse/HBASE-8479 Project: HBase Issue Type: Bug Components: build Affects Versions: 0.95.1 Reporter: stack Priority: Critical Fix For: 0.95.1 Attachments: attempt1.txt
With Roman, am trying to set up a bigtop ci of hbase 0.95 only we fail to compile. It is the exotic generics that are going on over in AggregateClient. Here is how we fail: {code} [ERROR] COMPILATION ERROR : [INFO] ------------------------------------------------------------- [ERROR] /mnt/jenkins/workspace/HBase-0.95/label/centos6/build/hbase/rpm/BUILD/hbase-0.95-SNAPSHOT/hbase-client/src/main/java/org/apache/hadoop/hbase/client/coprocessor/AggregationClient.java:[135,59] type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds Q,com.google.protobuf.Message [ERROR] /mnt/jenkins/workspace/HBase-0.95/label/centos6/build/hbase/rpm/BUILD/hbase-0.95-SNAPSHOT/hbase-client/src/main/java/org/apache/hadoop/hbase/client/coprocessor/AggregationClient.java:[208,59] type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds Q,com.google.protobuf.Message [ERROR] /mnt/jenkins/workspace/HBase-0.95/label/centos6/build/hbase/rpm/BUILD/hbase-0.95-SNAPSHOT/hbase-client/src/main/java/org/apache/hadoop/hbase/client/coprocessor/AggregationClient.java:[328,57] type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds T,com.google.protobuf.Message [ERROR] /mnt/jenkins/workspace/HBase-0.95/label/centos6/build/hbase/rpm/BUILD/hbase-0.95-SNAPSHOT/hbase-client/src/main/java/org/apache/hadoop/hbase/client/coprocessor/AggregationClient.java:[390,57] type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds T,com.google.protobuf.Message [ERROR] /mnt/jenkins/workspace/HBase-0.95/label/centos6/build/hbase/rpm/BUILD/hbase-0.95-SNAPSHOT/hbase-client/src/main/java/org/apache/hadoop/hbase/client/coprocessor/AggregationClient.java:[489,59] type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds T,com.google.protobuf.Message [ERROR] /mnt/jenkins/workspace/HBase-0.95/label/centos6/build/hbase/rpm/BUILD/hbase-0.95-SNAPSHOT/hbase-client/src/main/java/org/apache/hadoop/hbase/client/coprocessor/AggregationClient.java:[591,59] type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds T,com.google.protobuf.Message [INFO] 6 errors {code} I cannot reproduce locally but googling, I see that above is pretty common complaint when you move between compilers. Various are the recommendations for fix but none definitive. The easiest is dumbing down the generics which I tried but it only caused issues in other coprocessors. If clues on how to fix this, I'm all ears. Would like to get this bigtop ci build running. Its cool. -- This message is automatically generated by JIRA.
