Step 6. Validate the Connection to HDFS

Step 6. Validate the Connection to HDFS

Verify the connection to HDFS from the Data Vault Service and from the Data Vault Service plug-in in Data Archive.
Use the Data Vault Service
ssadrv
administration command to validate the connection to the HDFS Data Vault store.
On the machine that hosts the Data Vault Service, run the following command:
ssadrv –a hdfs://<Connection Name>/<Path to the Data Vault folder in HDFS>
For example, run the following command:
ssadrv –a hdfs://HDFS_Sales/data/sandqa1/infa_archive
In this command,
HDFS_Sales
is the name of the Hadoop connection defined in the ssa.ini file and
data/sandqa1/infa_archive
is the path to the Data Vault archive folder named
infa_archive
in the HDFS Data Vault store.
You can run the same command on the machine that hosts Data Archive to test the connection from Data Archive to HDFS.
