Suhas Satish created PIG-3667: --------------------------------- Summary: build.xml jar-all target does not include jython*.jar in lib/ directory Key: PIG-3667 URL: https://issues.apache.org/jira/browse/PIG-3667 Project: Pig Issue Type: Bug Components: build Affects Versions: 0.11.1, 0.12.0 Reporter: Suhas Satish Assignee: Suhas Satish
Pig package does not include the jython jar within lib/ directory with the jar-all ant target but includes it in the "ant package" target. It should be including it in both targets as often, the build/ directory is excluded from packaging which is where ivy puts all the dependency jars while building under build/ivy/lib/Pig To reproduce: ant jar-all rm -rf build/ bin/pig grunt> register '/tmp/test.py' using jython as myfunction; If done prior to installing jython, here's the error one gets: 2013-12-27 18:22:31,145 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2998: Unhandled internal error. org/python/core/PyObject Details at logfile: pig_*.log Within the pig_*.log => <log> Pig Stack Trace --------------- ERROR 2998: Unhandled internal error. org/python/core/PyObject java.lang.NoClassDefFoundError: org/python/core/PyObject at org.apache.pig.scripting.jython.JythonScriptEngine.registerFunctions(JythonScriptEngine.java:304) at org.apache.pig.PigServer.registerCode(PigServer.java:501) at org.apache.pig.tools.grunt.GruntParser.processRegister(GruntParser.java:436) at org.apache.pig.tools.pigscript.parser.PigScriptParser.parse(PigScriptParser.java:445) at org.apache.pig.tools.grunt.GruntParser.parseStopOnError(GruntParser.java:194) at org.apache.pig.tools.grunt.GruntParser.parseStopOnError(GruntParser.java:170) at org.apache.pig.tools.grunt.Grunt.run(Grunt.java:69) at org.apache.pig.Main.run(Main.java:538) at org.apache.pig.Main.main(Main.java:157) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.RunJar.main(RunJar.java:197) Caused by: java.lang.ClassNotFoundException: org.python.core.PyObject at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 14 more Fix: Including jython*.jar within the lib/ directory gets rid of this issue and the UDF can be loaded- grunt> register '/tmp/test.py' using jython as myfuncs; 2013-12-27 18:37:02,402 [main] INFO org.apache.pig.scripting.jython.JythonScriptEngine - created tmp python.cachedir=/tmp/pig_jython_4887743829482443898 2013-12-27 18:37:03,448 [main] WARN org.apache.pig.scripting.jython.JythonScriptEngine - pig.cmd.args.remainders is empty.
