------------------------------------
Summary: Consider not adding some jars when starting HMS
Key: IMPALA-11232
URL: https://issues.apache.org/jira/browse/IMPALA-11232
Project: IMPALA
Issue Type: Test
Components: Infrastructure
Affects Versions: Impala 4.0.0
Reporter: Fang-Yu Rao
Assignee: Fang-Yu Rao
Currently when we execute {{run-hive-server.sh}} with the "{{-with_ranger}}"
flag, we add all the jar files under the folder of
{{$RANGER_HOME/ews/webapp/WEB-INF/lib}} to '{{HADOOP_CLASSPATH}}' before we
call the shell script that starts the Hive service, i.e., {{bin/hive}}.
Recall that {{bin/hive}} would attempt to execute '{{hadoop version}}' to
determine the version of the underlying Hadoop distribution before starting the
Hive Metastore and the HiveServer2. By default, this Hadoop command under the
covers would add every path on '{{HADOOP_CLASSPATH}}' to its own environment
variable of '{{CLASSPATH}}'. When there are too many paths added to
'{{CLASSPATH}}', the Hadoop command would fail with the error message of
"{{Argument list too long.}}" and hence the Hive service could not be started.
We execute {{run-hive-server.sh}} with the "{{-with_ranger}}" flag in order to
run the end-to-end test of {{test_hive_with_ranger_setup}}. We should consider
not adding some (or all) of the jar files to '{{HADOOP_CLASSPATH}}' from the
folder described if some (or all) of them are not required to run the
end-to-end test so as to avoid the error mentioned above.
