+ * Purpose : 
+ *  This program will parse your apache log and store it into Hbase.
+ * 
+ * HowToUse : 
+ *  Make sure two thing :
+ *  1. Upload apache logs ( /var/log/apache2/access.log* ) to \ 
+ *    hdfs (default: /user/waue/apache-log) \
+ *   $ bin/hadoop dfs -put /var/log/apache2/ apache-log
+ *  2. parameter "dir" in main contains the logs.
+ *  3. you should filter the exception contents manually, \ 
+ *    ex:  ::1 - - [29/Jun/2008:07:35:15 +0800] "GET / HTTP/1.0" 200 729 "...
+ *  
+ * Check Result:
+ *  Go to hbase console, type : 
+ *    hql > select * from apache-log;
