flume+Hbase搭建问题详解

近期在做日志系统，所以选配了一些方案，在搭建时候遇到了问题，所以记录下

flume-ng去连接hbase

# Describe  the sink
a1.sinks.k1.type  = org.apache.flume.sink.hbase.AsyncHBaseSink
a1.sinks.k1.table = Router #设置hbase的表名
a1.sinks.k1.columnFamily = log #设置hbase中的columnFamily
a1.sinks.k1.serializer.payloadColumn=serviceTime,browerOS,clientTime,screenHeight,screenWidth,url,userAgent,mobileDevice,gwId,mac # 设置hbase的column
a1.sinks.k1.serializer = org.apache.flume.sink.hbase.BaimiAsyncHbaseEventSerializer # 设置serializer的处理类

重点说明几个属性 a1.sinks.k1.serializer.payloadColumn 中列出了所有的列名。a1.sinks.k1.serializer设置了flume serializer的处理类。BaimiAsyncHbaseEventSerializer类中会获取payloadColumn的内容，将它以逗号分隔，从而得出所有的列名。

因为flume-ng一般只支持简单的存入hbase

由于依赖的版本问题。此处需要将flume的lib 文件夹 下的protobuf用Hadoop-2.2.0中的2.5.0版本替换，还需要用hadoop-2.2.0中的guava替换flume的lib文件夹下的guava，删除原来相应的jar文件。启动即可生效。（PS：这是网上的说法，其实在用到最新的版本根本不需要这么搞）

在搭建hbase时候发成了这样的问题

依然缺少jar   htrace-core-2.04.jar 

这次启动没问题，但有个这个事情可能是我zookeeper没配置好

[ERROR - org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.checkIfBaseNodeAvailable(HConnectionManager.java:858)] The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

表示被占用了，好吧，我们给别的人换一个端口，后来发现还真不行，flume-ng自己不能配置端口了，所以只能修改编译了

看了很多文档也没写到底什么原因各种奇葩解决方法更多，最后无奈去看官方文档发现

zookeeperQuorum 参数，有看了源代码发现

 String zkQuorum = context.getString("zookeeperQuorum");

    Integer port = null;

    if ((zkQuorum != null) && (!zkQuorum.isEmpty())) {
      StringBuilder zkBuilder = new StringBuilder();
      logger.info(new StringBuilder().append("Using ZK Quorum: ").append(zkQuorum).toString());
      String[] zkHosts = zkQuorum.split(",");
      int length = zkHosts.length;
      for (int i = 0; i < length; i++) {
        String[] zkHostAndPort = zkHosts[i].split(":");
        zkBuilder.append(zkHostAndPort[0].trim());
        if (i != length - 1)
          zkBuilder.append(",");
        else {
          zkQuorum = zkBuilder.toString();
        }
        if (zkHostAndPort[1] == null) {
          throw new FlumeException("Expected client port for the ZK node!");
        }
        if (port == null)
          port = Integer.valueOf(Integer.parseInt(zkHostAndPort[1].trim()));
        else if (!port.equals(Integer.valueOf(Integer.parseInt(zkHostAndPort[1].trim())))) {
          throw new FlumeException("All Zookeeper nodes in the quorum must use the same client port.");
        }
      }

      if (port == null) {
        port = Integer.valueOf(2181);
      }

哈哈，问题就简单咯加个配置搞定

        at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1081)

又报拒绝连接，我勒个去，你不是内置的zookeeper吗，继续寻找真相,感觉flume-ng其实还是需要外置zookeeper，连接hbase时候两个zookeeper要一直的端口所以要和hbase的端口一致哦

搞定后发现出现了下面的问题
