HI All,
I am using Spark 1.6 and Pyspark.
I am trying to build a Randomforest classifier model using mlpipeline and
in python.
When I am trying to print the model I get the below value.
RandomForestClassificationModel (uid=rfc_be9d4f681b92) with 10 trees
When I use MLLIB RandomForest model
HI ,
If you need a data frame specific solution , you can try the below
df.select(from_unixtime(col("max(utcTimestamp)")/1000))

HI ,
You can try this
sqlContext.read.format("json").option("samplingRatio","0.1").load("path")
If it still takes time , feel free to experiment with the samplingRatio.
Thanks,
Vishnu

Try this
val customSchema = StructType(Array(
StructField("year", IntegerType, true),
StructField("make", StringType, true),
StructField("model", StringType, true)
))

HI All,
I am trying to use the VectorIndexer (FeatureExtraction) technique
available from the Spark ML Pipelines.
I ran the example in the documentation .
val featureIndexer = new VectorIndexer()
.setInputCol("features")
.setOutputCol("indexedFeatures")
.setMaxCategories(4)
.fit(data)
by my query.I need to
run the mentioned block again to use the UDF.
Is there is any way to maintain UDF in sqlContext permanently?
Thanks,
Vinod

Hi Siddarth,
It depends on what you are trying to solve. But the connectivity for
cassandra and spark is good .
The answer depends upon what exactly you are trying to solve.

You can use model.predict(point) that will help you identify the cluster
center and map it to the point.
rdd.map(x = (x,model.predict(x)))
