Daniel Dai commented on PIG-2457:
---------------------------------

PigStorage also fail with "-schema" option (before I thought it by default 
creates the schema file).

Yes, version mismatch is a bigger problem. In frontend, user can use 
"HADOOP_USER_CLASSPATH_FIRST" to override hadoop bundled jars, but for backend, 
hadoop always use bundled jars first. In our case, hadoop cannot find LRUMap in 
bundled jackson, so it goes to job.jar to find it. For Avro, it is not that 
lucky. I don't know a solution for that. We shall definitely push hadoop to 
bundled a newer jackson in next version (I am testing on 20.205).
