Hi Kien,

Thanks for you reply.

Your goal is to store the checkpoints in one hdfs cluster and the data in other hdfs cluster.

So the flink should be able to connect to two different hdfs clusters.

Thanks

Hi,

If your cluster are not high-availability clusters then just use the full path to the cluster.

For example, to refer to directory /checkpoint on cluster1, use hdfs://namenode1_ip:port/checkpoint

Like wise, /data on cluster2 will be hdfs://namenode2_ip:port/data


If your cluster is a HA cluster, then you need to modify the hdfs-site.xml like section 1 of this guide

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.4/bk_administration/content/distcp_between_ha_clusters.html

Then use the full path to the cluster hdfs://cluster1ha/checkpoint & hdfs://cluster2ha/data

Regards,
Kien

Thanks in advance,
