Zhenxiao Luo commented on HIVE-2015:
------------------------------------
Setting datanucleus.plugin.pluginRegistryBundleCheck has no effect of this bug.
According to:
http://www.datanucleus.org/products/datanucleus/persistence_properties.html
datanucleus.plugin.pluginRegistryBundleCheck
Description Defines what happens when plugin bundles are found and are
duplicated
Range of Values EXCEPTION | LOG | NONE
Seems this is set to whether LOG, EXCEPTION, or NONE if the plugin bundles are
found and are duplicated. If it is not found/unresolved, ERROR still shows up
in the first CLI command.
Also tested setting it to be EXCEPTION. No exception at all, the same error
message.

> Every time I start up the Hive CLI with logging enabled I'm treated to the
> following ERROR log messages courtesy of DataNucleus:
> {code}
> DEBUG metastore.ObjectStore: datanucleus.plugin.pluginRegistryBundleCheck =
> LOG
> ERROR DataNucleus.Plugin: Bundle "org.eclipse.jdt.core" requires
> "org.eclipse.core.resources" but it cannot be resolved.
> ERROR DataNucleus.Plugin: Bundle "org.eclipse.jdt.core" requires
> "org.eclipse.core.runtime" but it cannot be resolved.
> ERROR DataNucleus.Plugin: Bundle "org.eclipse.jdt.core" requires
> "org.eclipse.text" but it cannot be resolved.
> {code}
> Here's where this comes from:
> * The bin/hive scripts cause Hive to inherit Hadoop's classpath.
> * Hadoop's classpath includes $HADOOP_HOME/lib/core-3.1.1.jar, an Eclipse
> library.
> * core-3.1.1.jar includes a plugin.xml file defining an OSGI plugin
> * At startup, Datanucleus scans the classpath looking for OSGI plugins, and
> will attempt to initialize any that it finds, including the Eclipse OSGI
> plugins located in core-3.1.1.jar
> * Initialization of the OSGI plugin in core-3.1.1.jar fails because of
> unresolved dependencies.
> * We see an ERROR message telling us that Datanucleus failed to initialize a
> plugin that we don't care about in the first place.
> I can think of two options for solving this problem:
> # Rewrite the scripts in $HIVE_HOME/bin so that they don't inherit ALL of
> Hadoop's CLASSPATH.
> # Replace DataNucleus's NOnManagedPluginRegistry with our own implementation
> that does nothing.
