Apache Spark 0.8.1 is a maintenance and performance release for the Scala 2.9 version of Spark. It also adds several new features, such as standalone mode high availability, that will appear in Spark 0.9 but developers wanted to have in Scala 2.9. Contributions to 0.8.1 came from 41 developers.
### YARN 2.2 Support
-Support has been added for running Spark on YARN 2.2 and newer. Due to a change in the YARN API between previous versions and 2.2+, this was not supported in Spark 0.8.0. See the YARN documentation for specific instructions on how to build Spark for YARN 2.2+. We've also included a pre-compiled binary for YARN 2.2.

### High Availability Mode for Standalone Cluster Manager
-The standalone cluster manager now has a high availability (H/A) mode which can tolerate master failures. This is particularly useful for long-running applications such as streaming jobs and the shark server, where the scheduler master previously represented a single point of failure. Instructions for deploying H/A mode are included in the documentation. The current implementation uses Zookeeper for coordination.

### Spark SQL
-This release introduces [Spark SQL]({{site.url}}docs/latest/sql-programming-guide.html) as a new alpha component.

Under the hood, Spark SQL uses the Catalyst optimizer to choose an efficient execution plan, and can automatically push predicates into storage formats like Parquet. In future releases, Spark SQL will also provide a common API to other storage systems.

### Performance and Usability Improvements
Across the board, Spark 1.1 adds features for improved stability and performance, particularly for large-scale workloads. Spark now performs [disk spilling for skewed blocks](https://issues.apache.org/jira/browse/SPARK-1777) during cache operations, guarding against memory overflows if a single RDD partition is large. Disk spilling during aggregations, introduced in Spark 1.0, has been [ported to PySpark](https://issues.apache.org/jira/browse/SPARK-2538). This release introduces a [new shuffle implementation](https://issues.apache.org/jira/browse/SPARK-2045) optimized for very large scale shuffles. This “sort-based shuffle” will be become the default in the next release, and is now available to users. For jobs with large numbers of reducers, we recommend turning this on. This release also adds several usability improvements for monitoring the performance of long running or complex jobs. Among the changes are better [named accumulators](https://issues.apache.org/jira/browse/SPARK-2380) that display in Spark’s UI, [dynamic updating of metrics](https://issues.apache.org/jira/browse/SPARK-2099) for progress tasks, and [reporting of input metrics](https://issues.apache.org/jira/browse/SPARK-1683) for tasks that read input data.

The first is Spark’s communication manager used during bulk transfers, which upgrades to a [netty-based implementation](https://issues.apache.org/jira/browse/SPARK-2468). The second is Spark’s shuffle mechanism, which upgrades to the [“sort based” shuffle initially released in Spark 1.1](https://issues.apache.org/jira/browse/SPARK-3280). These both improve the performance and stability of very large scale shuffles. Spark also adds an [elastic scaling mechanism](https://issues.apache.org/jira/browse/SPARK-3174) designed to improve cluster utilization during long running ETL-style jobs. This is currently supported on YARN and will make its way to other cluster managers in future versions. Finally, Spark 1.2 adds support for Scala 2.11. For instructions on building for Scala 2.11 see the [build documentation](/docs/1.2.0/building-spark.html#building-for-scala-211).

### Spark Core
Spark 1.3 sees a handful of usability improvements in the core engine. The core API now supports [multi level aggregation trees](https://issues.apache.org/jira/browse/SPARK-5430) to help speed up expensive reduce operations. [Improved error reporting](https://issues.apache.org/jira/browse/SPARK-5063) has been added for certain gotcha operations. Spark's Jetty dependency is [now shaded](https://issues.apache.org/jira/browse/SPARK-3996) to help avoid conflicts with user programs. Spark now supports [SSL encryption](https://issues.apache.org/jira/browse/SPARK-3883) for some communication endpoints. Finaly, realtime [GC metrics](https://issues.apache.org/jira/browse/SPARK-3428) and [record counts](https://issues.apache.org/jira/browse/SPARK-4874) have been added to the UI.
