Ryan Compton created SPARK-1952:
-----------------------------------
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
```
