Description

In Windows, hadoop-config.cmd uses the non-existent-variable HADOOP_CORE_HOME when setting the JAVA_LIBRAR_PATH variable. It should use HADOOP_HOME or HADOOP_COMMON_HOME.
The net effect is that running e.g. "hdfs namenode" directly (outside of hadoop command prompt) would error out with UnsatisfiedLinkError because it can't access hadoop.dll.
