-----------------------------------

             Summary: slf4j version conflicts with pig
                 Key: SPARK-1952
                 URL: https://issues.apache.org/jira/browse/SPARK-1952
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.0.0
         Environment: pig 12.1 on Cloudera Hadoop, CDH3
            Reporter: Ryan Compton
             Fix For: 1.0.0


Upgrading from Spark-0.9.1 to Spark-1.0.0 causes all Pig scripts to fail when they "register" a jar containing Spark. The error appears to be related to org.slf4j.spi.LocationAwareLogger.log.

```
Caused by: java.lang.RuntimeException: Could not resolve error that
occured when launching map reduce job: java.lang.NoSuchMethodError:
org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V
at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher$JobControlThreadExceptionHandler.uncaughtException(MapReduceLauncher.java:598)
at java.lang.Thread.dispatchUncaughtException(Thread.java:1874)
```

To reproduce: compile Spark via ```$ SPARK_HADOOP_VERSION=0.20.2-cdh3u4 sbt/sbt assembly``` and register the resulting jar into a pig script. E.g.

```
REGISTER /usr/share/spark-1.0.0/assembly/target/scala-2.10/spark-assembly-1.0.0-SNAPSHOT-hadoop0.20.2-cdh3u4.jar;
data0 = LOAD 'data' USING PigStorage();
ttt = LIMIT data0 10;
DUMP ttt;
```

The Spark-1.0 jar includes some slf4j dependencies that were not present in 0.9.1

```
rfcompton@node19 /u/s/o/s/a/t/scala-2.10> jar tvf spark-assembly-1.0.0-SNAPSHOT-hadoop0.20.2-cdh3u4.jar | grep -i "slf" | grep LocationAware
  3259 Mon Mar 25 21:49:34 PDT 2013 org/apache/commons/logging/impl/SLF4JLocationAwareLog.class
   455 Mon Mar 25 21:49:22 PDT 2013 org/slf4j/spi/LocationAwareLogger.class
   479 Fri Dec 13 16:44:40 PST 2013 parquet/org/slf4j/spi/LocationAwareLogger.class
```

vs.

```
rfcompton@node19 /u/s/o/s/a/t/scala-2.10> jar tvf spark-assembly-0.9.1-hadoop0.20.2-cdh3u3.jar | grep -i "slf" | grep LocationAware
   455 Mon Mar 25 21:49:22 PDT 2013 org/slf4j/spi/LocationAwareLogger.class
```
