　　二、Hadoop中创建使用目录

root@m1:/home/hadoop# /home/hadoop/hadoop-2.2.0/bin/hadoop fs -mkdir /user/hive/warehouse/nginxlog
root@m1:/home/hadoop# /home/hadoop/hadoop-2.2.0/bin/hadoop fs -ls /user/hive/warehouse
Found 1 items
drwxr-xr-x   - root supergroup          0 2014-01-22 23:13 /user/hive/warehouse/nginxlog
root@m1:/home/hadoop#
　　三、Hive的日志表创建，并同步到Hbase中
　　　　1)创建自增长ID的java类UDFRowSequence.java,并添加到Hive环境中
　　#在Eclipse中创建Maven项目，然后使用Maven将项目打包成Jar文件，过程中需要引入hadoop-common-2.2.0.jar、hive-exec-0.13.1.jar这两个文件，可以在Hadoop2.2.0目录以及Hive0.13.1目录中找到。如果不会使用Maven将项目打包，可以参考这篇文章《Golang、Php、Python、Java基于Thrift0.9.1实现跨语言调用》中实现Java客户端部分，有如何打包的方法。
　　UDFRowSequence.java代码如下，使用Maven会打包成一个idoall.org-0.0.1-SNAPSHOT-jar-with-dependencies.jar文件，上传到Hive的lib目录下。本文后面会提供代码下载：

/**

 */
@Description(name = "row_sequence",
    value = "_FUNC_() - Returns a generated row sequence number starting from 1")
@UDFType(deterministic = false, stateful = true)
public class UDFRowSequence extends UDF
{
  private LongWritable result = new LongWritable();
 
  public UDFRowSequence() {
    result.set(0);
  }
 
  public LongWritable evaluate() {
    result.set(result.get() + 1);
    return result;
  }
}
　　　　2)在Hive中创建日志表
　　#然后将我们自定义的idoall.org-0.0.1-SNAPSHOT-jar-with-dependencies.jar，添加到Hive运行环境中

hive> ADD JAR /home/hadoop/hive-0.13.1/lib/idoall.org-0.0.1-SNAPSHOT-jar-with-dependencies.jar;

Added resource: /home/hadoop/hive-0.13.1/lib/idoall.org-0.0.1-SNAPSHOT-jar-with-dependencies.jar

　　#在Hive中创建自定义函数对数据进行处理，如果不想每次都执行这个命令，可以在hive-site.xml里面的<name>hive.aux.jars.path</name> 节点下面，把jar文件加到<value>节点中。

STORED AS TEXTFILE
location '/user/hive/warehouse/nginxlog';
　　　　3)将Nginx的日志数据导入到Hive日志表中
关于导入数据过程中overwrite的特性：
•目标表（或者分区）中的内容（如果有）会被删除，然后再将 filepath 指向的文件/目录中的内容添加到表/分区中。
•如果目标表（分区）已经有一个文件，并且文件名和 filepath 中的文件名冲突，那么现有的文件会被新文件所替代
如果不使用overwrite,改用into,只会增加记录。

　　　　　　方法三：通过如Flume、Kafka一类的工具监控日志数据，自动导入
　　　就不在这里细说，可以参考这两篇文章里面的实例，根据自己的业务需求修改代码：《Flume1.5.0的安装、部署、简单应用(含分布式、与hadoop2.2.0、hbase0.96的案例)》、《Flume+Kafka+Strom基于分布式环境的结合使用》
 
　　　　4)在Hive中创建Hbase可以识别的表
　　#在Hive中创建Hbase可以识别的表，相当于一张中间表了。同时将之前的测试数据导入到这张中间表，会自动同步到Hbase。

　　四、FAQ
　　1)如果导入的内容使用select查看时，发现是null，那可能是你的正则写的有问题，可以使用下面这个工具验证你的正则是否有问题。
　　#http://regex101.com，一个在线的正则表达式工具，很好用，如下图。
　　#在线测试通过后，将正则表达式，复制到一个文本文件中，进行两次转义字符的替换就可以使用了，第1次，将一个右斜杠去你的成两个右斜杠：'\'替换成'\\'；第二次将双引号替换成斜框双引号'"'替换成'\"'

Nginx日志导入到Hive0.13.1,同步Hbase0.96.2,设置RowKey为autoincrement(ID自增长)

 
　　2)如果提示“org.apache.hadoop.hive.contrib.serde2.RegexSerDe”相关的错误，请在hive中执行以下命令：
1
hive> add jar /home/hjl/hive/lib/hive_contrib.jar;
