HBase

执行日志

数据格式

hadoop fs -ls /warehouse/orc_elapsed_log

/warehouse/orc_elapsed_log/dt=20160101

执行脚本，Java的Hive脚本。

cd wangchenlong/workspace/user-profile/processor/profile

hadoop jar ./target/profile-1.1.1-jar-with-dependencies.jar me.chunyu.log_analysis.Main 20160101 20160131

hadoop fs -ls /tmp/wangchenlong/log_event

hadoop jar ./target/profile-1.1.1-jar-with-dependencies.jar me.chunyu.log_analysis.Main -h 20160601 20160731
hadoop jar ./target/profile-1.1.1-jar-with-dependencies.jar me.chunyu.log_analysis.Main -h 20160912 20161031
hadoop jar ./target/profile-1.1.1-jar-with-dependencies.jar me.chunyu.log_analysis.Main -h 20161214 20161231

Hive的Maven Jar包，与Orc包造成冲突，版本不同，导致类不同，一些方法找不到，参考。

java.lang.Exception: java.lang.NoSuchMethodError: org.apache.hadoop.hive.ql.exec.vector.VectorizedRowBatch.getDataColumnCount()
  at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:406)
Caused by: java.lang.NoSuchMethodError: org.apache.hadoop.hive.ql.exec.vector.VectorizedRowBatch.getDataColumnCount()
  at org.apache.orc.impl.RecordReaderImpl.nextBatch(RecordReaderImpl.java:1044)

原因是hive-exec和orc-mapreduce的hive-storage-api版本不同，导致VectorizedRowBatch类异常。

测试：

hadoop jar ./target/profile-1.1.1-jar-with-dependencies.jar me.chunyu.log_process.HiveMRDemo /tmp/wangchenlong/orc

解决方案，添加hive-storage-api，强制指定使用新的类。

<dependency>
    <groupId>org.apache.hive</groupId>
    <artifactId>hive-storage-api</artifactId>
    <version>2.4.0</version>
</dependency>

导入HBase

HDFS导入HBase，查看表

hbash shell
list
desc 'cy_event'
scan 'cy_event', {LIMIT=>5}  # 显示5个rowkey

表数据

 user_time|1488384000000|29768601          column=info:assess_num, timestamp=1505384441438, value=3
 user_time|1488384000000|29768601          column=info:duration, timestamp=1505384441438, value=42654
 user_time|1488384000000|29768601          column=info:event_name, timestamp=1505384441438, value=user_time
 user_time|1488384000000|29768601          column=info:event_time, timestamp=1505384441438, value=20170302_000000
 user_time|1488384000000|29768601          column=info:login_zone, timestamp=1505384441438, value=0
 user_time|1488384000000|29768601          column=info:uid, timestamp=1505384441438, value=29768601

执行数据，从HDFS导入HBase

cd wangchenlong/workspace/user-profile/processor/profile

hadoop jar ./target/profile-1.1.1-jar-with-dependencies.jar me.chunyu.log_analysis.Main -p 20170101 20170331
hadoop jar ./target/profile-1.1.1-jar-with-dependencies.jar me.chunyu.log_analysis.Main -p 20170401 20170731
hadoop jar ./target/profile-1.1.1-jar-with-dependencies.jar me.chunyu.log_analysis.Main -p 20170731 20170909

Processor业务类

public class UserTimeHBaseProcessor extends BaseSavedProcessor<LogEntity> {
    public static final String DEF_NAME = UserTimeHBaseProcessor.class.getSimpleName();
    @Override protected void onProcess(LogEntity entity) {
        super.onProcess(entity);

        String line = entity.original_line;
        String[] items = line.split("\\|");
        if (items.length != 6) {
            return;
        }

        Map<String, String> map = new HashMap<>();

        String uid = items[0];
        String event_name = items[1];
        String time = items[2];
        Date date = LaDateUtils.parseWriteDate(time);
        if (date == null) {
            return;
        }

        String login_zone = items[3];
        String duration = items[4];
        String assess_num = items[5];

        String rowKey = event_name + "|" + date.getTime() + "|" + uid;
        map.put("uid", uid);
        map.put("event_name", event_name);
        map.put("event_time", time);
        map.put("login_zone", login_zone);
        map.put("duration", duration);
        map.put("assess_num", assess_num);

        saveHBase(rowKey, map);
    }
}

注册Processor

public class ProcessorRegister extends BaseMainManager {
    private static class Holder {
        private static ProcessorRegister sInstance = new ProcessorRegister();
    }

    public static ProcessorRegister getInstance() {
        return Holder.sInstance;
    }

    private ProcessorRegister() {
        super();

        //++++++++++++++++++++ 处理器添加位置 ++++++++++++++++++++/
//        registerProcessor(UserTimeProcessor.DEF_NAME, new UserTimeProcessor());
        registerProcessor(UserTimeHBaseProcessor.DEF_NAME, new UserTimeHBaseProcessor());

        //++++++++++++++++++++ 处理器添加位置 ++++++++++++++++++++/
    }
}

执行

case "-p":
    main = new ProcessMain(args[1], args[2], LaValues.PathFormat.USER_TIME_PATH_FORMAT); // 进程模式
    break;

使用Log_Analysis分析框架

OK, that's all!
