Hi, My hadoop version is 0.20.203.0. And I also use Hive. The following is the exception I got.
Exception in thread "main" java.lang.NoSuchFieldError: ALLOW_UNQUOTED_CONTROL_CHARS at org.apache.hadoop.hive.ql.udf.generic.GenericUDTFJSONTuple.<clinit>(GenericUDTFJSONTuple.java:59) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) at org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:113) at org.apache.hadoop.hive.ql.exec.FunctionRegistry.registerGenericUDTF(FunctionRegistry.java:545) at org.apache.hadoop.hive.ql.exec.FunctionRegistry.registerGenericUDTF(FunctionRegistry.java:539) at org.apache.hadoop.hive.ql.exec.FunctionRegistry.<clinit>(FunctionRegistry.java:472) at org.apache.hadoop.hive.ql.session.SessionState.<init>(SessionState.java:202) at org.apache.hadoop.hive.cli.CliSessionState.<init>(CliSessionState.java:86) at org.apache.hadoop.hive.cli.CliDriver.run(CliDriver.java:635) at org.apache.hadoop.hive.cli.CliDriver.main(CliDriver.java:613) 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:156) I was told that the problem came from different versions used by Hadoop and Hive. So how can I resolve it. Thanks. Hsuan-Yi
