# Apache Hadoop 3.1.3 Release Notes
These release notes cover new developer and user-facing incompatibilities, important issues, features, and major improvements.
---
* [HADOOP-15922](https://issues.apache.org/jira/browse/HADOOP-15922) | *Major* | **DelegationTokenAuthenticationFilter get wrong doAsUser since it does not decode URL**
- Fix DelegationTokenAuthentication filter for incorrectly double encode doAs user parameter.
---
* [YARN-8761](https://issues.apache.org/jira/browse/YARN-8761) | *Major* | **Service AM support for decommissioning component instances**
- Component instance number is not linear increment when decommission feature is used. Application with assumption of linear increment component instance number maybe impacted by introduction of this feature.
---
* [HDFS-14305](https://issues.apache.org/jira/browse/HDFS-14305) | *Major* | **Serial number in BlockTokenSecretManager could overlap between different namenodes**
NameNodes rely on independent block token key ranges to communicate block token identities to DataNodes and clients in a way that does not create conflicts between the tokens issued by multiple NameNodes. HDFS-6440 introduced the potential for overlaps in key ranges; this fixes the issue by creating 64 possible key ranges that NameNodes assign themselves to, allowing for up to 64 NameNodes to run safely. This limitation only applies within a single Namespace; there may be more than 64 NameNodes total spread among multiple federated Namespaces.
---
* [HADOOP-16114](https://issues.apache.org/jira/browse/HADOOP-16114) | *Minor* | **NetUtils#canonicalizeHost gives different value for same host**
The above patch will resolve the race condition
---
* [HDFS-14396](https://issues.apache.org/jira/browse/HDFS-14396) | *Blocker* | **Failed to load image from FSImageFile when downgrade from 3.x to 2.x**
During a rolling upgrade from Hadoop 2.x to 3.x, NameNode cannot persist erasure coding information, and therefore a user cannot start using erasure coding feature until finalize is done.
