WebHDFS configuration

The WebHDFS feature must be enabled in order to use this connector.

Grant Read Permissions to Crawl Path

Granting READ permissions is a must since the connector won't be able to get any data if the Path to be crawled is restricted.

Kerberized Clusters

For Kerberized Clusters, a delegation token is required in order to crawl any path within the HDFS. To obtain this token you must:

1. SSH into your cluster.

2. Run:

   $ kinit <your-user-principal>
   $ curl -i --negotiate -u : "http://<host>:<port>/webhdfs/v1/?op=GETDELEGATIONTOKEN"
   ...
   {"Token":{"urlString":"<A-VERY-LONG-TOKEN>"}}

3. Copy the "Token" field and set it into the configuration of the connector.
