Connector error: HTTP/40X Status when connecting to WebHDFS


This error generally happens when the connector cannot access a Kerberized HDFS cluster. This may happen when:

  • You haven't configured a Delegation token to access the WebHDFS API
  • Your Delegation token is no longer available, in which case you should regenerate it and re-configure it.

Visit Prerequisites for more information.


If this happens after a few incremental crawls the incremental data will not be affected, so after this problem is resolved the incremental crawls can be resumed.
