捆綁HBase MapReduce作業(yè)

HBase JAR 也可作為一些捆綁 MapReduce 作業(yè)的驅(qū)動(dòng)程序。要了解捆綁的 MapReduce 作業(yè)，請(qǐng)運(yùn)行以下命令：

$ ${HADOOP_HOME}/bin/hadoop jar ${HBASE_HOME}/hbase-mapreduce-VERSION.jar
An example program must be given as the first argument.
Valid program names are:
  copytable: Export a table from local cluster to peer cluster
  completebulkload: Complete a bulk data load.
  export: Write table data to HDFS.
  import: Import data written by Export.
  importtsv: Import data in TSV format.
  rowcounter: Count rows in HBase table

每個(gè)有效的程序名都是捆綁的 MapReduce 作業(yè)。要運(yùn)行其中一個(gè)作業(yè)，請(qǐng)?jiān)谙旅娴氖纠鬄槟拿罱！?/p>
