Eric Yang created HDDS-1828:
-------------------------------
Summary: smoke test core-site.xml is confusing to user
Key: HDDS-1828
URL: https://issues.apache.org/jira/browse/HDDS-1828
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Eric Yang
In smoke test, Hadoop code is placed in /opt/hadoop, and Ozone code is placed
in /opt/ozone.
There are two copies of core-site.xml, one in $HADOOP_CONF_DIR, and another one
in $OZONE_CONF_DIR. When user look at the copy in $OZONE_CONF_DIR,
core-site.xml is empty. This may lead to assumption that hadoop is running
with local file system. Most application will reference to core-site.xml on
the classpath. Hence, it depends on how the application is carefully setup to
avoid using $OZONE_CONF_DIR as a single node Hadoop. It may make sense to
symlink $OZONE_CONF_DIR to $HADOOP_CONF_DIR to prevent mistakes.
