-----------------------------
Summary: Should verify matching Spark versions at launch
Key: ZEPPELIN-443
URL: https://issues.apache.org/jira/browse/ZEPPELIN-443
Project: Zeppelin
Issue Type: Bug
Components: Core, Interpreters
Affects Versions: 0.5.6
Reporter: Amos
Zeppelin or the SparkInterpreter should, at launch, check to confirm that the
current SPARK_HOME matches the same version of Spark that was used when
Zeppelin was built.
If Zeppelin is run with a different Spark version in SPARK_HOME than was used
when Zeppelin was built, attempting to start spark from the SparkInterpreter is
likely to fail with an exception. But the exception varies depending on the
particular version-mismatch (class not found, method not found, inconsistent
dependency library versions, etc.), and none of the error messages are helpful.
The correct behavior is to detect this and fail early -- or at least report it
properly.
