I want to pretty print the result of a correlation in a zeppelin notebook: val Row(coeff: Matrix) = Correlation.corr(data, "features").head One of the ways to achieve this is to convert the result into a DataFrame with each value in a separate column and call z.show() . However, looking into the Matrix api I don't see any way to do this. Is there another straight forward way to achieve this? Edit: The dataframe has 50 columns. Just converting to a string would not help as the output get truncated. Using the toString method should be the easiest and fastest way if you simply want to print the

I am using Presto and Zeppelin. There are a lot of raw datas. I have to summarize those datas.

I am trying to set up zeppelin-0.8.0 on my windos 8 r2 OS. I have already running spark on my console i.e. SPARK_HOME and JAVA_HOME, HADOOP_HOME set up and running fine.

I'm writing a code where I'm fetching a dataset using an internal library and %pyspark interpreter. However I am unable to pass the dataset to %python interpreter. I tried using string variables and it is working fine, but with dataset I'm using the following code to put dataset in a zeppelin context- z.put("input_data",input_data) and it is throwing the following error: AttributeError: 'DataFrame' object has no attribute '_get_object_id' . Can you please tell me how can I do this? Thanks in advance. You can put the result in ResourcePool via print it to %table. %python print('%table a\tb\n408

Apache Zeppelin has good support for AngularJS . While there is a gap between Scala and Javascript. I am trying to add Highcharts support to Zeppelin to fill in this gap. The main goal is to plot it simply directly from Spark DataFrame . After couple round refactor, I come up with the following interface. github.com/knockdata/zeppelin-highcharts Here are two options. Which option is better? Option A This is an example to plot highcharts. highcharts(bank, "marital", List("name" -> "age", "y" -> avg(col("balance")), "orderBy" -> col("age")), new Title("Marital Job Average Balance").x(-20), new

In the " Zeppelin tutorial " notebook, I can't use the %sql interpreter . It will output " sql interpreter not found ". But the spark commands work fine, as well as %md and %sh .
