HADOOP_CRL_CHECK for NetBackup servers and clients

The HADOOP_CRL_CHECK option lets you specify the revocation check level for external certificates of the Hadoop server. Based on the check, revocation status of the Hadoop server certificate is validated against the certificate revocation list (CRL) during host communication.

By default, the HADOOP_CRL_CHECK option is disabled. If you want to validate the revocation status of the Hadoop server certificate against certificate revocation list (CRL), set the option to a different value.

You can choose to use the CRLs from the directory that is specified for the ECA_CRL_PATH configuration option or the CRL distribution point (CDP).

See ECA_CRL_PATH for NetBackup servers and clients.

Table: HADOOP_CRL_CHECK information

Usage

Description

Where to use

On all backup hosts.

How to use

Use the nbgetconfig and the nbsetconfig commands to view, add, or change the option.

For information about these commands, see the NetBackup Commands Reference Guide.

Use the following format:

HADOOP_CRL_CHECK = CRL check

You can specify one of the following:

  • DISABLE (or 0) - Revocation check is disabled. Revocation status of the certificate is not validated against the CRL during host communication. This is the default value.

  • LEAF (or 1) - Revocation status of the leaf certificate is validated against the CRL.

  • CHAIN (or 2) - Revocation status of all certificates from the certificate chain are validated against the CRL.
