Yanwen Lin created KYLIN-3871:
---------------------------------
Summary: Kylin inside Cloudera CDH Quickstart Sandbox
Key: KYLIN-3871
URL: https://issues.apache.org/jira/browse/KYLIN-3871
Project: Kylin
Issue Type: Test
Components: Job Engine
Affects Versions: v2.6.0
Environment: Cloudera Quickstart Docker image:
- OS: centos6
- memory: 13GB
- disk: 20GB
- java: 1.8
- maven: 3.5.3
Reporter: Yanwen Lin
When doing integration test, I met the following error. I know this is related
to Java version error and the reason is that Kylin use java1.8 while Cloudera
use java1.7. So I manually installed java 1.8 and set JAVA_HOME to point to
Spark2.x. (I also type spark-submit --version to check this). But the bug did
not go away. I guess during the process of Spark job, some command may change
the Java version back to java1.7 (not sure). Is there anyway to force it not
change back to Java1.7 or any workaround?
I have successfully finished maven installing and unit tests.
