adoroszlai opened a new pull request #2415: URL: https://github.com/apache/hadoop/pull/2415
## What changes were proposed in this pull request? 1. Update to Hadoop 3.3.0 release. 2. And some misc updates/improvements for the docker build: * Use current Apache Rat 0.13 in `build.sh` as 0.12 is now available only in archive. * Add `.dockerignore` to speed up build (avoid sending `.git` etc. to the Docker daemon). * Let git ignore `build` dir (created by `build.sh`). * Add some MapReduce-related env to docker config to allow running MR examples. https://issues.apache.org/jira/browse/HADOOP-17320 ## How was this patch tested? Built the new image locally: ``` $ ./build.sh ... Successfully built 2adf1981fb31 Successfully tagged apache/hadoop:3 ``` and tested it with the included sample Docker Compose cluster: ``` $ docker-compose up -d --scale datanode=3 --scale nodemanager=3 $ docker-compose exec resourcemanager yarn jar /opt/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.3.0.jar pi 3 3 ... Job Finished in 26.524 seconds Estimated value of Pi is 3.55555555555555555556 ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
