To query the size of a table in HBase, you can use the count command in the HBase shell. The specific steps are as follows:

  1. Open the HBase shell and connect to the HBase database.
  2. We can use the count command to query the number of rows in a table, for example:
count 'table_name'
  1. Calculate the size of the table based on the number of rows and the size of each row of data. For a more accurate calculation, you can use the HBase API to retrieve the size of each row of data and then calculate the cumulative total.

Additionally, you can also use Hadoop’s command-line tool hadoop fs -du -h /hbase/data/default/table_name to inquire about the size of the data in an HBase table, which is a more direct and accurate method.
