50.捆绑的 HBase MapReduce 作业

HBase JAR 还可用作某些捆绑 MapReduce 作业的驱动程序。要了解捆绑的 MapReduce 作业，请运行以下命令。

$ ${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

每个有效的程序名称都捆绑了 MapReduce 作业。 要运行其中一个作业,请根据以下示例构建命令.

$ ${HADOOP_HOME}/bin/hadoop jar ${HBASE_HOME}/hbase-mapreduce-VERSION.jar rowcounter myTable
