Namit Jain commented on HIVE-2466:
----------------------------------

    [javac] Compiling 680 source files to /data/users/njain/hive_commit2/build/ql/classes
    [javac] /data/users/njain/hive_commit2/ql/src/java/org/apache/hadoop/hive/ql/exec/MapJoinOperator.java:191:

    [javac] location: class org.apache.hadoop.hive.ql.exec.Utilities
    [javac]         String filePath = Utilities.generatePath(baseDir, pos, currentFileName);


Can you refresh ?

I am getting the above error in compiling.
Also, create a arc diff entry for helping reviewing.
