Since #110 was reverted, I have updated this PR to include the original behavioral changes to local mode as well as the documentation and unit test updates. |

This would be an incompatible interface change (which is why tests needed to be modified !). Btw, Runtime.getRuntime.availableProcessors() can return varying values (vm's) includes ht cores, etc .. |
|
This is an incompatible change, which is why it is targeted for 1.0. It is my opinion that this is how it should've been in the first place; since Spark is inherently a distributed system, it doesn't make sense for an out-of-the-box "spark-shell" to run on one thread. We use availableProcessors() elsewhere in the Spark codebase, and here it is used only as a reasonable default. "local" mode is only intended for testing purposes, so the impact and severity of this change is limited. (Also I'd like to point out that the tests that needed to be modified were actually making false assumptions about partition ordering that just happened to work out since it was using 1 thread.) |

If we were adding support for local today a variant of this PR would be a There are bunch of MT unsafe code which uses local (should have been
We use that api in only one other place - which is pretty similar to this, 'local' is very commonly used by our users, so it is not restricted to
That would point to probably broken tests. Regards,

@mridulm Taking in your comments, I realized that my main concern was that people new to spark who run spark-shell or pyspark for the first time are probably expecting their code to run in parallel on multiple cores. Therefore, instead of breaking "local" mode, I modified the PR to add a "local[*]" mode which has the behavior of using all your machine's logical cores. This becomes the new default for spark-shell and pyspark, but otherwise all other code paths are unaffected. Does this seem reasonable? |

Sounds good, as long as there is no behavioural change for existing code/scripts which use 'local' as the default in most cases, additional semantics are fine - atleast by me ! |

Can one of the admins verify this patch? |
This is the default mode for running spark-shell and pyspark, intended to allow users running spark for the first time to see the performance benefits of using multiple cores, while not breaking backwards compatibility for users who use "local" mode and expect exactly 1 core.

This pull requests integrates SparkR, an R frontend for Spark. The SparkR package contains both RDD and DataFrame APIs in R and is integrated with Spark's submission scripts to work on different cluster managers. Some integration points that would be great to get feedback on: 1. Build procedure: SparkR requires R to be installed on the machine to be built. Right now we have a new Maven profile `-PsparkR` that can be used to enable SparkR builds 2. YARN cluster mode: The R package that is built needs to be present on the driver and all the worker nodes during execution. The R package location is currently set using SPARK_HOME, but this might not work on YARN cluster mode. The SparkR package represents the work of many contributors and attached below is a list of people along with areas they worked on edwardt (edwart) - Documentation improvements Felix Cheung (felixcheung) - Documentation improvements Hossein Falaki (falaki) - Documentation improvements Chris Freeman (cafreeman) - DataFrame API, Programming Guide Todd Gao (7c00) - R worker Internals Ryan Hafen (hafen) - SparkR Internals Qian Huang (hqzizania) - RDD API Hao Lin (hlin09) - RDD API, Closure cleaner Evert Lammerts (evertlammerts) - DataFrame API Davies Liu (davies) - DataFrame API, R worker internals, Merging with Spark Yi Lu (lythesia) - RDD API, Worker internals Matt Massie (massie) - Jenkins build Harihar Nahak (hnahak87) - SparkR examples Oscar Olmedo (oscaroboto) - Spark configuration Antonio Piccolboni (piccolbo) - SparkR examples, Namespace bug fixes Dan Putler (dputler) - Dataframe API, SparkR Install Guide Ashutosh Raina (ashutoshraina) - Build improvements Josh Rosen (joshrosen) - Travis CI build Sun Rui (sun-rui)- RDD API, JVM Backend, Shuffle improvements Shivaram Venkataraman (shivaram) - RDD API, JVM Backend, Worker Internals Zongheng Yang (concretevitamin) - RDD API, Pipelined RDDs, Examples and EC2 guide Author: Shivaram Venkataraman <[email protected]> Author: Shivaram Venkataraman <[email protected]> Author: Zongheng Yang <[email protected]> Author: cafreeman <[email protected]> Author: Shivaram Venkataraman <[email protected]> Author: Davies Liu <[email protected]> Author: Davies Liu <[email protected]> Author: hlin09 <[email protected]> Author: Sun Rui <[email protected]> Author: lythesia <[email protected]> Author: oscaroboto <[email protected]> Author: Antonio Piccolboni <[email protected]> Author: root <edward> Author: edwardt <[email protected]> Author: hqzizania <[email protected]> Author: dputler <[email protected]> Author: Todd Gao <[email protected]> Author: Chris Freeman <[email protected]> Author: Felix Cheung <[email protected]> Author: Hossein <[email protected]> Author: Evert Lammerts <[email protected]> Author: Felix Cheung <[email protected]> Author: felixcheung <[email protected]> Author: Ryan Hafen <[email protected]> Author: Ashutosh Raina <[email protected]> Author: Oscar Olmedo <[email protected]> Author: Josh Rosen <[email protected]> Author: Yi Lu <[email protected]> Author: Harihar Nahak <[email protected]> Closes #5096 from shivaram/R and squashes the following commits: da64742 [Davies Liu] fix Date serialization 59266d1 [Davies Liu] check exclusive of primary-py-file and primary-r-file 55808e4 [Davies Liu] fix tests 5581c75 [Davies Liu] update author of SparkR f731b48 [Shivaram Venkataraman] Only run SparkR tests if R is installed 64eda24 [Shivaram Venkataraman] Merge branch 'R' of https://github.com/amplab-extras/spark into R d7c3f22 [Shivaram Venkataraman] Address code review comments Changes include 1.

See databricks/universe#14909 (comment) > The original reason for using minimal-json in `spark-redshift` was to not pull in a heavierweight dependency like Jackson, which would have been trickier to do when this library was supporting Spark 1.4.x through 1.6.x (since those have different Jackson versions, etc). I'd be fine with rewriting this code to drop that dependency. Thus this patch updates the code to use Json4s and Jackson, similar to what's used already in Spark's `JsonProtocol` classes. Author: Josh Rosen <[email protected]> Closes apache#182 from JoshRosen/SC-5650.
