Hadoop Configuration

Place all the modified XML configurations (e.g. core-site.xml) for Hadoop in ./conf/hadoop/. Note that the . refers to the directory of your own Dockerfile. Unmodified XML files need not appear in the directory, but at least one XML file must be present due to the limitation of COPY command.

Kerberos Configuration

Place the modified krb5.conf for Kerberos in ./conf/krb5/krb5.conf. Note that the . refers to the directory of your own Dockerfile. This file must be present for the ONBUILD COPY to work.
