> - HDFS Pre-Upgrade Check Change No Longer Requires HA
> Note: For users who are upgrading from champlain-m10 and onwards to dal, and have “truncate” feature enabled in HDFS, rolling upgrade is NOT supported. Check following flag in hdfs-site.xml to see if “truncate” is enabled: “dfs.allow.truncate” = “true”
> - NameNode Configuration Change For Ranger
> Note: If Ranger is enabled, then there is a configuration change needed in the NameNode configurations to ensure that Ranger authorization will function with HDP 2.3.
> Edit {{hdfs-site.xml}} with the following change:
> If Ranger is enabled, configure “dfs.namenode.inode.attributes.provider.class” with the ranger’s plugin class name “org.apache.ranger.authorization.hadoop.RangerHdfsAuthorizer”
> If ranger is disabled, this configuration must not be there.
> Configure Ranger KMS in hdfs-site.xml
> The key is “dfs.encryption.key.provider.uri”
