# This configuration file is used by the apache-hbase clusterdock topology to populate configuration
# files for an HBase cluster. Section names denote the filenames (e.g. [hadoop/core-site.xml]) with
# the section's corresponding items denoting properties.
#
# Filenames ending with .xml will have items run through an XML parser. That is,
#
# [hbase/hbase-site.xml]
# hbase.cluster.distributed = true
#
# would lead to the creation of an hbase-site.xml file containing:
#
# <property>
#   <name>hbase.cluster.distributed</name>
#   <value>true</value>
# </property>
#
# Note, also, that items in non-xml files can be copied verbatim by with using the "body:" item (be
# sure to include leading whitespace must be used for the following lines). For example:
#
# [hbase/hbase-env.sh]
# body:
#     COMMON_HBASE_OPTS="$COMMON_HBASE_OPTS -XX:+UseG1GC"
#     COMMON_HBASE_OPTS="$COMMON_HBASE_OPTS -XX:+PrintGCDetails"
#
# would result in an hbase-env.sh file with:
#
#     COMMON_HBASE_OPTS="$COMMON_HBASE_OPTS -XX:+UseG1GC"
#     COMMON_HBASE_OPTS="$COMMON_HBASE_OPTS -XX:+PrintGCDetails"
#
# Two last notes:
# 1. Items starting with +++ will be eval'd with Python directly.
# 2. As defined in action.py, some wildcards are processed at cluster start time (e.g. {network}).
