+1 (non-binding, of course)
1. Compiled OSX 10.10 (Yosemite) OK Total time: 14:50 min
mvn clean package -Pyarn -Dyarn.version=2.6.0 -Phadoop-2.4
-Dhadoop.version=2.6.0 -Phive -DskipTests -Dscala-2.11
2. Tested pyspark, mlib - running as well as compare results with 1.1.x &
1.2.x
2.1. statistics (min,max,mean,Pearson,Spearman) OK
2.2. Linear/Ridge/Laso Regression OK
But MSE has increased from 40.81 to 105.86. Has some refactoring happened
on SGD/Linear Models ? Or do we have some extra parameters ? or change
of defaults ?
2.3. Decision Tree, Naive Bayes OK
2.4. KMeans OK
Center And Scale OK
WSSSE has come down slightly
2.5. rdd operations OK
State of the Union Texts - MapReduce, Filter,sortByKey (word count)
2.6. Recommendation (Movielens medium dataset ~1 M ratings) OK
Model evaluation/optimization (rank, numIter, lmbda) with itertools
OK
3. Scala - MLlib
3.1. statistics (min,max,mean,Pearson,Spearman) OK
3.2. LinearRegressionWIthSGD OK
3.3. Decision Tree OK
3.4. KMeans OK
3.5. Recommendation (Movielens medium dataset ~1 M ratings) OK
Cheers

P.S: For some reason replacing "import sqlContext.createSchemaRDD" with "
import sqlContext.implicits._" doesn't do the implicit conversations.
registerTempTable
gives syntax error. I will dig deeper tomorrow. Has anyone seen this ?
