Hi: A few months ago, I was building Flink and ran into shading issues for flink-dist as described in your docs. We resolved this in BigTop by adding the correct way to build flink-dist in the do-component-build script and everything was fine after that.
Now, I’m running into issues doing the same now in Flink 1.2.0 and I’m trying to figure out what’s changed and how to fix it. Here’s how the flink-dist jar looks with proper shading: jar -tvf /usr/lib/flink/lib/flink-dist_2.10-1.1.4.jar | grep HttpConnectionParams 2485 Tue Jan 01 00:00:00 UTC 1980 org/apache/flink/hadoop/shaded/org/apache/commons/httpclient/params/HttpConnectionParams.class 3479 Tue Jan 01 00:00:00 UTC 1980 org/apache/flink/hadoop/shaded/org/apache/http/params/HttpConnectionParams.class When I build Flink 1.2.0 in BigTop, here’s shading for the jar found in the RPM: jar -tvf flink-dist_2.10-1.2.0.jar | grep HttpConnectionParams 2392 Tue Jan 01 00:00:00 GMT 1980 org/apache/commons/httpclient/params/HttpConnectionParams.class 2485 Tue Jan 01 00:00:00 GMT 1980 org/apache/flink/hadoop/shaded/org/apache/commons/httpclient/params/HttpConnectionParams.class 3479 Tue Jan 01 00:00:00 GMT 1980 org/apache/flink/hadoop/shaded/org/apache/http/params/HttpConnectionParams.class 2868 Tue Jan 01 00:00:00 GMT 1980 org/apache/http/params/HttpConnectionParams.class I thought maybe it was some strange thing going on with BigTop, so then I tried just straight building Flink 1.2.0 (outside BigTop) and get the same shading: jar -tvf flink-dist_2.10-1.2.0.jar | grep HttpConnectionParams 2485 Fri Mar 17 05:41:16 GMT 2017 org/apache/flink/hadoop/shaded/org/apache/commons/httpclient/params/HttpConnectionParams.class 3479 Fri Mar 17 05:41:16 GMT 2017 org/apache/flink/hadoop/shaded/org/apache/http/params/HttpConnectionParams.class 2392 Fri Mar 17 05:41:24 GMT 2017 org/apache/commons/httpclient/params/HttpConnectionParams.class 2868 Fri Mar 17 05:41:24 GMT 2017 org/apache/http/params/HttpConnectionParams.class And, yes, this is after going into flink-dist and running mvn clean install again since I am using Maven 3.3.x. Here’s a snippet from my Maven version: mvn -version Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T16:41:47+00:00) Maven home: /usr/local/apache-maven Java version: 1.8.0_121, vendor: Oracle Corporation Any ideas on what my problem might be here? Thanks, Craig
