Write elasticsearch's data directly on HDFS rather than on local filesystem

Elastic Stack Elasticsearch

Hi,

I have an elasticsearch cluster running on kubernetes. Currently elasticsearch writing indices data on local filesystem (path: /usr/share/elasticsearch/data) as shown below.

Since elasticsearch is producing a very large amount of data, So I want to write this data directly on hadoop filesystem rather than on local filesystem.

Is there any simplest way to do this ??

Note: I am not telling about Snapshot/Restore which is mentioned here https://www.elastic.co/guide/en/elasticsearch/reference/7.6/snapshot-restore.html

Data should always be on a local filesystem/volumes in order to be accessed as fast and efficient as possible.

You could use HDFS for something like snapshots, but not the data currently in use.
