Description

Acceptance test is broken by new Hadoop 3 docker image. KMS container fails to start with:

2020-11-16 14:03:22,641 ERROR [main] conf.Configuration (Configuration.java:loadResource(3047)) - error parsing conf file:/etc/hadoop/core-site.xml
java.io.FileNotFoundException: /etc/hadoop/core-site.xml (No such file or directory)

The problem is that the new hadoop:3 image is based on more recent hadoop-runner, which sets HADOOP_CONF_DIR, whereas previously it was unset.

ENV HADOOP_CONF_DIR=/etc/hadoop
