adoroszlai opened a new pull request, #6273: URL: https://github.com/apache/hadoop/pull/6273
## What changes were proposed in this pull request? * Clean yum cache after installing `which` to reduce image size by ~230MB. * Reorder installation of Hadoop and `which`. Hadoop release bits are not going to change, but we may want to install other packages in the image. The updated order reduces the number of image layers that have to be downloaded after such future change. https://issues.apache.org/jira/browse/HADOOP-18973 ## How was this patch tested? ``` $ docker pull apache/hadoop:2 $ docker run -it --rm apache/hadoop:2 du -sh /var/cache/yum 234M /var/cache/yum $ ./build.sh ...
