* SPARK-1173. Improve scala streaming docs.Aaron Kimball2014-03-021-5/+33
| | | | | | | | | | | | | Clarify imports to add implicit conversions to DStream and fix other small typos in the streaming intro documentation. Tested by inspecting output via a local jekyll server, c&p'ing the scala commands into a spark terminal. Author: Aaron Kimball <aaron@magnify.io> Closes #64 from kimballa/spark-1173-streaming-docs and squashes the following commits: 6fbff0e [Aaron Kimball] SPARK-1173. Improve scala streaming docs.

* SPARK-1121: Include avro for yarn-alpha buildsPatrick Wendell2014-03-021-4/+0
| | | | | | | | | | | | | | | | | This lets us explicitly include Avro based on a profile for 0.23.X builds. It makes me sad how convoluted it is to express this logic in Maven. @tgraves and @sryza curious if this works for you. I'm also considering just reverting to how it was before. The only real problem was that Spark advertised a dependency on Avro even though it only really depends transitively on Avro through other deps. Author: Patrick Wendell <pwendell@gmail.com> Closes #49 from pwendell/avro-build-fix and squashes the following commits: 8d6ee92 [Patrick Wendell] SPARK-1121: Add avro to yarn-alpha profile

* SPARK-1135: fix broken anchors in docsMatei Zaharia2014-02-261-28/+1
| | | | | | | | | | | | | | A recent PR that added Java vs Scala tabs for streaming also inadvertently added some bad code to a document.ready handler, breaking our other handler that manages scrolling to anchors correctly with the floating top bar. As a result the section title ended up always being hidden below the top bar. This removes the unnecessary JavaScript code.

This is still a work in progress, but the major changes are in place. So feedback is most welcome. In general, I have tried to make the guide to easier to understand even if the reader does not know much about Spark. The updated website is hosted here - http://www.eecs.berkeley.edu/~tdas/spark_docs/streaming-programming-guide.html The major changes are: - Overview illustrates the usecases of Spark Streaming - various input sources and various output sources - An example right after overview to quickly give an idea of what Spark Streaming program looks like - Made Java API and examples a first class citizen like Scala by using tabs to show both Scala and Java examples (similar to AMPCamp tutorial's code tabs) - Highlighted the DStream operations updateStateByKey and transform because of their powerful nature - Updated driver node failure recovery text to highlight automatic recovery in Spark standalone mode - Added information about linking and using the external input sources like Kafka and Flume - In general, reorganized the sections to better show the Basic section and the more advanced sections like Tuning and Recovery. Todos: - Links to the docs of external Kafka, Flume, etc - Illustrate window operation with figure as well as example.

|\ | | | | | | | | | | Allow files added through SparkContext.addFile() to be overwritten This is useful for the cases when a file needs to be refreshed and downloaded by the executors periodically. For example, a possible use case is: the driver periodically renews a Hadoop delegation token and writes it to a token file. The token file needs to be downloaded by the executors whenever it gets renewed. However, the current implementation throws an exception when the target file exists and its contents do not match those of the new source. This PR adds an option to allow files to be overwritten to support use cases similar to the above.

Further, n should be less than m. The decomposition is computed by first computing *A^TA = V S^2 V^T*, computing svd locally on that (since n x n is small), from which we recover S and V. Then we compute U via easy matrix multiplication as *U = A * V * S^-1* Only singular vectors associated with the largest k singular values If there are k such values, then the dimensions of the return will be: * *S* is *k x k* and diagonal, holding the singular values on diagonal. * *U* is *m x k* and satisfies U^T*U = eye(k). * *V* is *n x k* and satisfies V^TV = eye(k). All input and output is expected in sparse matrix format, 0-indexed as tuples of the form ((i,j),value) all in RDDs. # Testing Tests included. They test: - Decomposition promise (A = USV^T) - For small matrices, output is compared to that of jblas - Rank 1 matrix test included - Full Rank matrix test included - Middle-rank matrix forced via k included # Example Usage import org.apache.spark.SparkContext import org.apache.spark.mllib.linalg.SVD import org.apache.spark.mllib.linalg.SparseMatrix import org.apache.spark.mllib.linalg.MatrixyEntry // Load and parse the data file val data = sc.textFile("mllib/data/als/test.data").map { line => val parts = line.split(',') MatrixEntry(parts(0).toInt, parts(1).toInt, parts(2).toDouble) } val m = 4 val n = 4 // recover top 1 singular vector val decomposed = SVD.sparseSVD(SparseMatrix(data, m, n), 1) println("singular values = " + decomposed.S.data.toArray.mkString) # Documentation Added to docs/mllib-guide.md
