raicho created SPARK-11142:
------------------------------
Summary: org.datanucleus is already registered
Key: SPARK-11142
URL: https://issues.apache.org/jira/browse/SPARK-11142
Project: Spark
Issue Type: Question
Components: Spark Shell
Affects Versions: 1.5.1
Environment: Windows7 Home Basic
Reporter: raicho
Fix For: 1.5.1
I first setup Spark this Wednesday on my computer. When I executed
spark-shell.cmd, warns shows on the screen like "org.datanucleus is already
registered. Ensure you don't have multiple JAR versions of the same plugin in
the classpath. The URL "file:/c:/spark/lib/datanucleus-core-3.2.10.jar" is
already registered and you are trying to register an identical plugin located
at URL "file:/c:/spark/bin/../lib/datanucleus-core-3.2.10.jar" " and
"org.datanucleus.api.jdo is already registered. Ensure you don't have multiple
JAR versions of the same plugin in the classpath. The URL
"file:/c:/spark/lib/datanucleus-core-3.2.6.jar" is already registered and you
are trying to register an identical plugin located at URL
"file:/c:/spark/bin/../lib/datanucleus-core-3.2.6.jar" "
The two URLs shown in fact mean the same path. I tried to find the classpath in
the configuration files but failed. No other codes outside has been executed on
spark yet.
What happened and how to deal with the warn?
