Assume that an HBase table Student is disabled. So, how to access the student table once it is disabled, by using Scan command?
Answer / Naveen Kumar Sonia
To scan a disabled table using the Scan command, you first need to enable the table before running the scan. However, disabling a table means that data can no longer be written or read directly from it. To access the data, you would usually export the table as a CSV file and then import it into another HBase table.
