Assignee: Zhenxiao Luo
@Zhenxiao: Please see if setting
datanucleus.plugin.pluginRegistryBundleCheck=NONE fixes this problem. If it
does, please prepare a patch. Thanks!
> Eliminate bogus Datanucleus.Plugin Bundle ERROR log messages
> ------------------------------------------------------------

> Key: HIVE-2015
> URL: https://issues.apache.org/jira/browse/HIVE-2015
> Project: Hive
> Issue Type: Bug
> Components: Diagnosability, Metastore
> Reporter: Carl Steinbach
> Assignee: Zhenxiao Luo

> 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.
