How does Hbase support Bulk data loading?

Answer»

There are two main steps to do a data bulk load in Hbase.

  • Generate Hbase data file(StoreFile) using a custom mapreduce job) from the data source. The StoreFile is created in Hbase internal format which can be efficiently loaded.

  • The prepared file is imported using another tool like comletebulkload to import data into a running cluster. Each file gets loaded to one specific region.
