/**
 * Program: LogParserGo.java
 * Editor: Waue Chen 
 * From :  NCHC. Taiwn
 * Last Update Date: 07/02/2008
 */
/**
 * 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;
