To check the amount of data in HBase, you can use either the HBase Shell or the HBase Java API. Here are examples of using both the HBase Shell and Java API.<\/p>\n

    \n
  1. Using HBase Shell:<\/li>\n
  2. Open the terminal and launch the HBase Shell.<\/li>\n
  3. Enter the following command to retrieve the amount of data in the table: hbase(main):001:0> count ‘table_name’<\/li>\n
  4. Using the Java API of HBase:<\/li>\n
  5. Import the HBase dependency in a Java project.<\/li>\n
  6. Create an HBase configuration object and an HBase connection object.<\/li>\n
  7. Create an HBase Admin object using a connection object.<\/li>\n
  8. Obtain information about the RegionServer and Regions of the table using the Admin object.<\/li>\n
  9. Iterating through RegionServers and Regions, getting the amount of data for each Region and summing them up.<\/li>\n
  10. Finally, you will receive the total amount of data from the entire table.<\/li>\n
  11. The code above is used to calculate the size of data stored in an HBase table using Java. It creates a connection to the HBase cluster, retrieves information about the regions of the table, scans each region to calculate the size of data in bytes, and finally prints out the total data size.<\/li>\n
  12. Please make sure to replace “table_name” with the actual name of the table from which you want to retrieve data.<\/li>\n<\/ol>\n

    The above demonstrates how to view the data volume in HBase using HBase Shell and Java API. You can choose either method according to your needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
