![]() ![]() The following screenshot shows the output. Then select settings and make the following changes: Select the Bar Chart icon to change the display. Then select 65 from the Temp drop-down list. Paste this snippet in a new paragraph and press SHIFT ENTER. Select buildingID, date, targettemp, (targettemp - actualtemp) as temp_diff from hvac where targettemp > "$" When you first run the query, a drop-down is automatically populated with the values you specified for the variable. The next snippet shows how to define a variable, Temp, in the query with the possible values you want to query with. You can also run Spark SQL statements using variables in the query. settings, appear after you have selected Bar Chart, allows you to choose Keys, and Values. The %sql statement at the beginning tells the notebook to use the Livy Scala interpreter. Select buildingID, (targettemp - actualtemp) as temp_diff, date from hvac where date = "6/1/13" Also the difference between the target and actual temperatures for each building on a given date. Paste the following query in a new paragraph. You can now run Spark SQL statements on the hvac table. %spark2 interpreter is not supported in Zeppelin notebooks across all HDInsight versions, and %sh interpreter will not be supported from HDInsight 4.0 onwards. From the right-hand corner of the paragraph, select the Settings icon (sprocket), and then select Show title. You can also provide a title to each paragraph. The screenshot looks like the following image: The output shows up at the bottom of the same paragraph. The status on the right-corner of the paragraph should progress from READY, PENDING, RUNNING to FINISHED. Press SHIFT ENTER or select the Play button for the paragraph to run the snippet. Register as a temporary table called "hvac" ![]() Val hvacText = sc.textFile("wasbs:///HdiSamples/HdiSamples/SensorSampleData/hvac/HVAC.csv")Ĭase class Hvac(date: String, time: String, targettemp: Integer, actualtemp: Integer, buildingID: String) Create an RDD using the default Spark context, sc ![]() The above magic instructs Zeppelin to use the Livy Scala interpreter In the empty paragraph that is created by default in the new notebook, paste the following snippet. When you create a Spark cluster in HDInsight, the sample data file, hvac.csv, is copied to the associated storage account under \HdiSamples\SensorSampleData\hvac. It's denoted by a green dot in the top-right corner. From the header pane, navigate to Notebook > Create new note.Įnter a name for the notebook, then select Create Note.Įnsure the notebook header shows a connected status. Replace CLUSTERNAME with the name of your cluster:Ĭreate a new notebook. I even added additional components for use cases that would be helpful in the future, such as a JIRA badge and an update log.You may also reach the Zeppelin Notebook for your cluster by opening the following URL in your browser. After some testing with the team and several iterations, I ended up with a group of useful everyday tools. I started by creating a few demo components that could help us do things like show the current status of design flows, leave notes, or chat with a team member. Once again, with the help of auto layout these annotations could expand dynamically when adding text. The answer was yes! I came up with the idea of annotations that could be used to communicate directly in Figma. Could we utilize Figma’s built-in features to help us communicate more efficiently in our workspace? No more waiting for another person to finish with a file, because we were all working simultaneously on it. Designing as a team was faster than we had ever imagined. One of the key benefits of transitioning to Figma, was our ability to collaborate in the same workspace. ![]()
