Importing SQL to a CQL table or CFS (deprecated)
Steps for importing SQL data into a CQL table or the Cassandra File System.
Note: Hadoop is deprecated for use with DataStax Enterprise. DSE
Hadoop and BYOH (Bring Your Own Hadoop) are deprecated. Sqoop is also deprecated and
will be removed when Hadoop is removed.
To import data to CQL, the
keyspace and CQL table must exist prior to the importation. If the CQL table
contains data prior to the importation, cql-import updates the data. The Sqoop demo shows how to import SQL data into a CQL table. In addition to importing data to a CQL table, you can also import data to the Cassandra File System (CFS). The CFS is the Cassandra counterpart to the Hadoop Distributed File System (HDFS). The example in this section shows how to import SQL data to CFS. Using Hive and other utilities, you can access the CFS data.
