The title is a bit weird as I'm having difficulties narrowing down the problem. I used my solution on Hadoop 2.0.0-cdh4.4.0 and hive 0.10 without issues.
- I can't create a table using this SerDe: https://github.com/rcongiu/Hive-JSON-Serde
first try:
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. org.apache.hadoop.hive.serde2.objectinspector.primitive.AbstractPrimitiveJavaObjectInspector.<init>(Lorg/apache/hadoop/hive/serde2/objectinspector/primitive/PrimitiveObjectInspectorUtils$PrimitiveTypeEntry;)V
second try:
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. Could not initialize class org.openx.data.jsonserde.objectinspector.JsonObjectInspectorFactory
I can create a table with this SerDe: https://github.com/cloudera/cdh-twitter-example
I create an external table with tweets from flume. I can't do "SELECT * FROM tweets;"
FAILED: RuntimeException org.apache.hadoop.hive.ql.metadata.HiveException: Failed with exception java.lang.ClassNotFoundException: com.cloudera.hive.serde.JSONSerDejava.lang.RuntimeException: java.lang.ClassNotFoundException: com.cloudera.hive.serde.JSONSerDe
I can do SELECT id, text FROM tweets;
- I can do a SELECT COUNT(*) FROM tweets;
I can't self join this table:
Execution log at: /tmp/jochen.debie/jochen.debie_20140311121313_164611a9-b0d8-4e53-9bda-f9f7ac342aaf.log 2014-03-11 12:13:30 Starting to launch local task to process map join; maximum memory = 257294336 Execution failed with exit status: 2 Obtaining error information
Task failed! Task ID: Stage-5
mentioned execution log:

org.apache.hadoop.hive.ql.metadata.HiveException: Failed with exception java.lang.ClassNotFoundException: com.cloudera.hive.serde.JSONSerDejava.lang.RuntimeException: java.lang.ClassNotFoundException: com.cloudera.hive.serde.JSONSerDe
Does anyone know how to fix this or at least show me where the problem is?
EDIT: Can it be a problem that I built the serde on a Hadoop 2.0.0-cdh4.4.0 and hive 0.10?
