0.18.2 release compiled with java 6 ?
Dear Hadoop Developers,
i work on a java 5 project and during upgrade from 0.18.1 to 0.18.2
this error appears:
...
x.java:[11,-1] cannot access org.apache.hadoop.streaming.JarBuilder
bad class file: /Users/jz/.m2/repository/org/apache/hadoop/hadoop-
streaming/0.18.2/hadoop-streaming-0.18.2.jar(org/apache/hadoop/
streaming/JarBuilder.class)
class file has wrong version 50.0, should be 49.0
...
Could it that 0.18.2 is compiled with java 6 whereas 0.18.1 is
compiled with java 5 ?
If so, would there be any plans to republish or do another release ?
thanks
Johannes

Or just run `ant jar` from $HADOOP_HOME and grab the jar (postfixed with
-dev) in $HADOOP_HOME/build.

You can also rebuild the jar by compiling all the sources in the 'src' folder with your working jdk.
