Hi folks, I just sent off https://gerrit.cloudera.org/#/c/9743/ and https://issues.apache.org/jira/browse/IMPALA-4277 for GVD, which changes the default minicluster to be based on Hadoop 3.0, Hive 2.1, Sentry 2.0, and so on. This change *will not* be back-ported to 2.x.
When you pull that change in, you'll need to re-build your minicluster with, e.g., ./buildall.sh -testdata -format -notests. This will pull in the new dependencies, format your cluster, and load up all the data. As you know, it takes 1-2 hours. If you want to hold off, you can elso set export IMPALA_MINICLUSTER_PROFILE_OVERRIDE=2 in your environment. Note that this choice between versions happens at build time, and CMake depends on it. So, switching back and forth requires re-running CMake. Please let me know if you run into any trouble. This is a big enough that there may be some bumps on the road. -- Philip
