【问题描述】:
我正在尝试运行一个简单的 MapReduce 进程来编写 HFile,以便稍后导入到 HBase 表中。
作业提交时:
hbase com.pcoa.Driver /test /bulk pcoa
我收到以下异常,表明 netty-3.6.6.Final.jar 在 HDFS 中不存在(但它确实存在于此处)。
-rw-r--r--+ 1 mbeening flprod 1206119 Sep 18 18:25 /dedge1/hadoop/hbase-0.96.1.1-hadoop2/lib/netty-3.6.6.Final.jar
恐怕我不明白如何解决这个配置(?)错误。
谁能给我一些建议?
这里是例外:

这是我的驱动程序:
public class Driver {
public static void main(String[] args) throws Exception {
Configuration conf = new Configuration();
Job job = new Job(conf, "HBase Bulk Import");
job.setJarByClass(HBaseKVMapper.class);
job.setMapperClass(HBaseKVMapper.class);
job.setMapOutputKeyClass(ImmutableBytesWritable.class);
job.setMapOutputValueClass(KeyValue.class);
job.setInputFormatClass(TextInputFormat.class);
HTable hTable = new HTable(conf, args[2]);
HFileOutputFormat.configureIncrementalLoad(job, hTable);
FileInputFormat.addInputPath(job, new Path(args[0]));
FileOutputFormat.setOutputPath(job, new Path(args[1]));
job.waitForCompletion(true);
}
}
【问题讨论】:
-
注意:我在 hadoop 2.2.0,hbase 0.96.1.1,zookeeper 3.4.5
-
我是否可以提供任何其他信息来帮助我了解问题所在。根本不明白为什么进程要在HDFS系统中找这个jar?
-
不使用此 HFile 写入进程的进程在我的集群上似乎可以正常工作 - 但我的负载的单记录插入无法正常工作。真诚感谢您提供的任何帮助。谢谢!
