ECS 3.6.2 Data Access Guide

Verify Hadoop access to ECS

You must verify access to the ECS bucket.

Once all Hadoop client services have started, ensure that you can access the ECS bucket using the Hadoop CLI. The URI is of the form viprfs://bucket.namespace.federation/.

For a bucket with URI viprfs://hive-warehouse-1.ns1.federation1/, you can attempt a directory listing using: 
[root@mycluster1-master-0 ~]# hdfs dfs -ls viprfs://hive-warehouse-1.ns1.federation1/
A new bucket will be empty and nothing will be returned.
For the same bucket, the following commands create an empty file and then perform a directory listing that shows the file. 

[root@mycluster1-master-0 ~]# hdfs dfs -touchz viprfs://hive-warehouse-1.ns1.federation1/hive-warehouse-1
[root@mycluster1-master-0 ~]# hdfs dfs -ls viprfs://hive-warehouse-1.ns1.federation1/
