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
