---------------------------------
Summary: Use OZONE_CLASSPATH instead of HADOOP_CLASSPATH
Key: HDDS-2218
URL: https://issues.apache.org/jira/browse/HDDS-2218
Project: Hadoop Distributed Data Store
Issue Type: Task
Components: docker
Reporter: Marton Elek
HADOOP_CLASSPATH is the standard way to add additional jar files to the
classpath of the mapreduce/spark/.. .jobs. If something is added to the
HADOOP_CLASSPATH, than it should be on the classpath of the classic hadoop
daemons.
But for the Ozone components we don't need any new jar files (cloud connectors,
libraries). I think it's more safe to separated HADOOP_CLASSPATH from
OZONE_CLASSPATH. If something is really need on the classpath for Ozone daemons
the dedicated environment variable should be used.
Most probably it can be fixed in
hadoop-hdds/common/src/main/bin/hadoop-functions.sh
And the hadoop-ozone/dev/src/main/compose files also should be checked (some of
them contain HADOOP_CLASSPATH
