Review Comment:
   Because of the way we add mask with patterns
   ```
   add(toPatternPair(PATH_HDFS_WITH_DATE_USER_GROUP_REGEX, String.format("%s 
%s$3%s %s $6%s",
       HDFS_USER_MASK, HDFS_GROUP_MASK, HDFS_SIZE_MASK, HDFS_DATE_MASK, 
HDFS_MASK)));
   ```
   Here, we can't distinguish between 0 and non-zero values to decide whether 
to use HDFS_SIZE_MASK or not. So , I had to add another regex to make it work
