各位。我正在用mr处理一些日志文件，文件在hdfs上。我想从文件中检索一些信息并将它们存储到hbase。
所以我开始工作

HADOOP_CLASSPATH=`${HBASE_HOME}/bin/hbase classpath` ${HADOOP_HOME}/bin/hadoop jar crm_hbase-1.0.jar /datastream/music/useraction/2014-11-30/music_useraction_20141130-230003072+0800.24576015364769354.00018022.lzo

如果我只是以“hadoop jar x”运行作业，它会显示“not find hbaseconfiguration”
我的代码很简单，

public int run(String[] strings) throws Exception {
    Configuration config = HBaseConfiguration.create();  
    String  kerbConfPrincipal = "ndir@HADOOP.HZ.NETEASE.COM";
    String  kerbKeytab = "/srv/zwj/ndir.keytab";
    UserGroupInformation.loginUserFromKeytab(kerbConfPrincipal, kerbKeytab);
    UserGroupInformation ugi = UserGroupInformation.getLoginUser();
    System.out.println(" auth: " + ugi.getAuthenticationMethod());
    System.out.println(" name: " + ugi.getUserName());
    System.out.println(" using keytab:" + ugi.isFromKeytab());
    HBaseAdmin.checkHBaseAvailable(config);
    //set job name
    Job job = new Job(config, "Import from file ");
    job.setJarByClass(LogRun.class);
    //set map class
    job.setMapperClass(LogMapper.class);
    //set output format and output table name
    job.setOutputFormatClass(TableOutputFormat.class);
    job.getConfiguration().set(TableOutputFormat.OUTPUT_TABLE, "crm_data");
    job.setOutputKeyClass(ImmutableBytesWritable.class);
    job.setOutputValueClass(Put.class);
    job.setNumReduceTasks(0);
    TableMapReduceUtil.addDependencyJars(job);

但是当我试图运行这个mr时，我无法执行“context.write（null，put）”，似乎“map”在这一行停止了。我认为这与“kerbkeytab”有关，是不是意味着我在运行“map”过程时需要“login”
