  Slider is a collection of tools and technologies to package, deploy, and
  manage long running applications on Apache Hadoop YARN clusters.

  Three most important issues to address in the move towards graduation:
  
-   1.
-   2.
-   3.
+ 1. Apache Slider community/PPMC had voted to move portions of Slider into
+    Apache Hadoop YARN as modules. In the first week of November 2017,
+    the Apache Hadoop community voted in favor to merge all Slider specific
+    changes (now referred to as YARN Service) from a feature branch to
+    Hadoop trunk. As per the current release plan, it is expected to be GA in
+    Apache Hadoop release 3.1.0. It is possible that the remaining pieces
+    of Slider will be moved at a later point in time or become obsolete or
+    evolve to work closely with YARN.
  
+ 2. Getting more external users.
+ 
+ 3. Growth of a diverse set of developers/committers/PMC members.

+ How has the project developed since the last report?
+ 
+    Work continues in parallel on the Apache Hadoop trunk branch and on
+    the Slider podling. The bulk of the work has been in Hadoop trunk. A
+    Yarnfile (specification for YARN Service) for the Hive/LLAP application
+    was committed to the Slider yarn-native-services branch. Hive/LLAP
+    is a Slider application on top of Apache Hadoop 2.x. The commit of
+    this Yarnfile paves the way for all existing owners of Slider applications
+    to migrate their existing application package scripts to Apache
+    Hadoop 3.1.x.
