I got OOM on running create-release script in branch-2.10.

$ ./dev-support/bin/create-release --docker --dockercache
$ tail -n 14 patchprocess/mvn_install.log

I got no issue when I build the RC of 2.10.1 using the Dockerfile. JDK migration to Zulu by HADOOP-17572 might be related.

Increasing maximum heap and perm gen size a bit worked for me.
