【Flume】flume输出sink到hbase的实现

flume 1.5.2

hbase 0.98.9

hadoop 2.6

zk 3.4.6

以上是基础的软件及对应版本，请先确认以上软件安装成功！

1、添加jar包支持

将hbase的lib下的这些jar包拷贝到flume的lib下

2、配置flume

注意看以上的serializer配置，采用的是官方的RegexHbaseEventSerializer，

当然还有一个SimpleHbaseEventSerializer

如果你使用了SimpleHbaseEventSerializer

就会出现如下的错误

当然这个序列化器应该自己来开发的，因为列族，列修饰符什么的，应该由我们自己定义的

3、测试
这里注意，你必须提前在hbase将表创建好

hbase(main):004:0> create 'flume','chiwei'
0 row(s) in 1.0770 seconds

=> Hbase::Table - flume

待监测的文件内容为

Hello Flume
Hello HBase
Hello Hadoop
Hello Zk
Hello chiwei

hbase(main):006:0> scan 'flume'
