charlesconnell opened a new pull request, #6293: URL: https://github.com/apache/hadoop/pull/6293
### Description of PR This PR adds two new boolean settings to DataNodes: - `dfs.datanode.block.access.token.unsafe.allowed-not-required` - `dfs.datanode.unsafe.sasl.allowed-not-required` With these two new settings, it is now possible for a Hadoop cluster with HDFS to enable secure mode without downtime. Please see the included documentation changes for more detailed discussion, and usage recommendations. ### How was this patch tested? My employer (HubSpot) used a version of this patch on our internal fork of Hadoop to transition all of our HBase clusters into secure mode, without major incident. The company's SaaS product is running on secure-mode HBase clusters now. ### For code changes: - [x] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799.
