Мирон commented on HIVE-18849:
------------------------------
This works with java 9 deployed as following:
C:\dev\java
standing on this directory
C:\dev\git\hadoop\hive\standalone-metastore\target\classes
with package.jdo
under same
java -classpath
C:\dev\git\hadoop\hive\standalone-metastore\target\classes;C:\Users\hadoop\.m2\repository\org\datanucleus\datanucleus-core\5.1.7\datanucleus-core-5.1.7.jar;C:\Users\hadoop\.m2\repository\org\datanucleus\datanucleus-rdbms\5.1.6\datanucleus-rdbms-5.1.6.jar;C:\Users\hadoop\.m2\repository\org\datanucleus\javax.jdo\3.2.0-m8\javax.jdo-3.2.0-m8.jar;C:\Users\hadoop\.m2\repository\org\datanucleus\datanucleus-api-jdo\5.1.4\datanucleus-api-jdo-5.1.4.jar
org.datanucleus.enhancer.DataNucleusEnhancer -v -api JDO
C:\dev\git\hadoop\hive\standalone-metastore\target\classes\org\apache\hadoop\hive\metastore\model\MDatabase.class
DataNucleusEnhancer version 5.1.6 ( latest release in the repository ) invoked
manually works without issues, too. In other words, as far as code / tool goes,
enhancer works. Takes a bit of an effort to learn the infrastructure to get to
the details. Feel free to take over at any time, since I can be pulled into
something else at any moment. For the moment assigning to self.
