Hi there,
Howdy. I just updated hadoop from 0.11.2 to 0.12.0 and getting the following
error.

Hi Hairong,
Howdy. Thanks for the patch. I applied the patch you had submitted but
something is wrong with the checksum patch. I'm not able to compile my code
with the patch.
compile-core:
[javac] Compiling 38 source files to D:\GOLD\dev\search\searchng
\build\classes
[javac]
D:\GOLD\dev\search\searchng\src\java\com\gale\searchng\workflow\fetcher\ConcurrentFetcherParser.java:21:
cannot access org.apache.hadoop.streaming.StreamXmlRecordReader
[javac] bad class file: D:\GOLD\dev\search\searchng\lib\hadoop-
streaming.jar (org/apache/hadoop/streaming/StreamXmlRecordReader.class)
[javac] class file has wrong version 50.0, should be 49.0
[javac] Please remove or make sure it appears in the correct
subdirectory of the classpath.
[javac] import org.apache.hadoop.streaming.StreamXmlRecordReader;
[javac] ^
[javac] 1 error
BUILD FAILED
