一、环境
Hadoop集群：使用Ambari搭建
Debug:Windows10 + jdk 1.8.0 +maven
二、步骤
2.1 创建Maven项目
2.2 配置文件
从Ambari中下载Hbase配置文件hbase-site.xml，并放在项目：
/src/main/resources/hbase
2.3 将配置路径加入到classpath
2.3 给pom.xml添加依赖
我的pom.xml最终如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</dependencies>
</project>
2.4 添加log配置文件log4j2.xml
路径：\src\main\java\log4j2.xml
log4j2.xml文件内容：
<?xml version="1.0" encoding="UTF-8"?>
<!--设置log4j2的自身log级别为warn-->
<configuration status="debug">
<appenders>
<console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="[%d{yyyy-MM-dd HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
</console>
<RollingFile name="RollingFileInfo" fileName="${sys:user.home}/logs/DTCenterDataApplication/info.log"
filePattern="${sys:user.home}/logs/DTCenterDataApplication/$${date:yyyy-MM}/info-%d{yyyy-MM-dd}-%i.log">
<Filters>
<ThresholdFilter level="INFO"/>
<ThresholdFilter level="WARN" onMatch="DENY" onMismatch="NEUTRAL"/>

<Policies>
<TimeBasedTriggeringPolicy/>
<SizeBasedTriggeringPolicy size="100 MB"/>
</Policies>
</RollingFile>
<RollingFile name="RollingFileWarn" fileName="${sys:user.home}/logs/DTCenterDataApplication/warn.log"
filePattern="${sys:user.home}/logs/DTCenterDataApplication/$${date:yyyy-MM}/warn-%d{yyyy-MM-dd}-%i.log">

<ThresholdFilter level="ERROR" onMatch="DENY" onMismatch="NEUTRAL"/>
</Filters>

</RollingFile>
<RollingFile name="RollingFileError" fileName="${sys:user.home}/logs/DTCenterDataApplication/error.log"
filePattern="${sys:user.home}/logs/DTCenterDataApplication/$${date:yyyy-MM}/error-%d{yyyy-MM-dd}-%i.log">
<ThresholdFilter level="ERROR"/>

<Policies>
<TimeBasedTriggeringPolicy/>
<SizeBasedTriggeringPolicy size="100 MB"/>
</Policies>
</RollingFile>
</appenders>
<loggers>
<!--过滤掉spring和hibernate的一些无用的debug信息-->
<logger name="org.springframework" level="INFO">
</logger>
<logger name="org.hibernate" level="INFO">
</logger>
<root level="all">
<appender-ref ref="Console"/>
<appender-ref ref="RollingFileInfo"/>
<appender-ref ref="RollingFileWarn"/>
<appender-ref ref="RollingFileError"/>
</root>
</loggers>
</configuration>
2.5 创建Hbase测试程序
package com.th.test.demo1;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.util.Bytes;
import java.io.IOException;
public class HbasePutExample {
@SuppressWarnings("deprecation")
public static void main(String[] args) throws IOException{
Configuration conf = HBaseConfiguration.create();
HTable table = new HTable(conf,"testtable");
Put put = new Put(Bytes.toBytes("myrow-2"));
put.add(
Bytes.toBytes("colfam1"),
Bytes.toBytes("qual1"),
Bytes.toBytes("val1"));
put.add(
Bytes.toBytes("colfam1"),
Bytes.toBytes("qual2"),
Bytes.toBytes("val2"));
table.put(put);
}
}
2.6运行
控制台日志输出：
2.7 查看执行结果
