How to import/export hbase data via hdfs (hadoop commands)

Question

I have saved my crawled data by nutch in Hbase whose file system is hdfs. Then I copied my data (One table of hbase) from hdfs directly to some local directory by command

Answer 1

If you want to export the table from one hbase cluster and import it to another, use any one of the following method:

Using Hadoop

• Export

  $ bin/hadoop jar  export \
         [ [ []]
  

  NOTE: Copy the output directory in hdfs from the source to destination cluster

• Import

  $ bin/hadoop jar  import  
  

Note: Both outputdir and inputdir are in hdfs.

Using Hbase

• Export

  $ bin/hbase org.apache.hadoop.hbase.mapreduce.Export \
       [ [ []]]
  

• Copy the output directory in hdfs from the source to destination cluster

• Import

  $ bin/hbase org.apache.hadoop.hbase.mapreduce.Import
