== What justifies a -1 vote for this release? ==
This vote is happening relatively late into the QA period, so
-1 votes should only occur for significant regressions from
1.0.2. Bugs already present in 1.1.X, minor
regressions, or bugs related to new features will not block this

== What default changes should I be aware of? ==
1. The default value of "spark.shuffle.blockTransferService" has been
changed to "netty"
--> Old behavior can be restored by switching to "nio"

2. The default value of "spark.shuffle.manager" has been changed to "sort".
--> Old behavior can be restored by setting "spark.shuffle.manager" to "hash".

== How does this differ from RC1 ==
This has fixes for a handful of issues identified - some of the
notable fixes are:

SPARK-4498: Standalone Master can fail to recognize completed/failed

SPARK-4552: Query for empty parquet table in spark sql hive get
SPARK-4753: Parquet2 does not prune based on OR filters on partition columns
SPARK-4761: With JDBC server, set Kryo as default serializer and
disable reference tracking
SPARK-4785: When called with arguments referring column fields, PMOD throws NPE
