elek commented on issue #814: HDDS-1518. Use /etc/ozone for configuration inside docker-compose URL: https://github.com/apache/hadoop/pull/814#issuecomment-491745153 Note: we create config files based on name convention: FILENAME_EXT_key=value will be converted to FILENAME.EXT. As CONF is a valid extension name (to generate spark/kafka/zookeeper conf, can't remember exactly which one) HADOOP_CONF_DIR should be excluded. To test: * Apply the patch * build the conainer with ./build.sh * tag it: docker tag apache/hadoop-runner:latest apache/hadoop-runner:jdk11 * Start any of the compose based environments of ozone To double check: ``` docker diff ozone_scm_1 C /etc C /etc/hadoop A /etc/hadoop/log4j.properties.raw A /etc/hadoop/log4j2.properties A /etc/hadoop/log4j2.properties.raw A /etc/hadoop/ozone-site.xml A /etc/hadoop/ozone-site.xml.raw A /etc/hadoop/hdfs-site.xml A /etc/hadoop/hdfs-site.xml.raw A /etc/hadoop/log4j.properties C /opt A /opt/transformation.pyc A /data C /tmp A /tmp/hsperfdata_hadoop A /tmp/hsperfdata_hadoop/72 A /tmp/librocksdbjni3381692124588853026.so A /tmp/hadoop-hadoop-scm.pid ``` As you can see the etc folder is used for configuration.
