does the back-end storage support HDFS when using The Apache Ignite?

Question

On the Overview site(https://ignite.apache.org/docs/latest/extensions-and-integrations/ignite-for-spark/overview), when you are using Apache Ignite, the back-end storage is HDFS. I don't see how to use HDFS on this link ---> https://ignite.apache.org/docs/latest/persistence/external-storage

Answer 1

Ignite doesn’t ship an out-of-the-box implementation of its CacheStore interface for HDFS. You can implement it yourself or keep Ignite and HDFS in sync by other means: https://www.gridgain.com/docs/latest/integrations/datalake-accelerator/getting-started
