I couldn't find any evidence of using WebHDFS client in. OSD clusters, still checking

Comment 7 Jonathan Christison 2021-02-12 15:16:34 UTC 
Marking Red Hat JBoss Fuse 6, Red Hat Fuse 7 and Red Hat Integration Camel K as being affected but at a low impact, although all products distribute and use artifacts in the affected range ie. org.apache.hadoop:hadoop-hdfs:jar:* as part of camel-hdfs2 and camel-hdfs neither component uses the vulnerable WebHDFS client functionality and webhdfs URIs are not supported.
Comment 10 Przemyslaw Roguski 2021-03-29 13:21:51 UTC 
Statement:

While OpenShift Container Platform (OCP) does package a vulnerable version of hadoop-hdfs-client in the hadoop and hive containers, the HDFS storage back-end is not enabled by default and is largely undocumented/unsupported. However, as it still can be enabled by using the configuration option `unsupportedFeatures.enabledHDFS`, the vulnerability has been rated Moderate for OCP.

In OpenShift Container Platform (OCP), the Hive/Presto/Hadoop components that comprise the OCP Metering stack, ship the vulnerable version of hadoop package.
Since the release of OCP 4.6, the Metering product has been deprecated [1], hence the affected components are marked as wontfix.
This may be fixed in the future.
