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 Na [...]
+
+

+
+* [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.

+
+<p>The most important difference is that unlike GFS, Hadoop DFS files
+have strictly one writer at any one time. Bytes are always appended
+to the end of the writer's stream. There is no notion of "record appends"
+or "mutations" that are then checked or reordered. Writers simply emit
+a byte stream. That byte stream is guaranteed to be stored in the
