Hi @Alexander Daher. In the commits dropdown (see image) you can probably select a <strong>previous<\/strong> commit to return to that <strong>version<\/strong>.<\/p>\n<\/p>\n<p>In this regard, what is the difference between Zeppelin and Jupyter <strong>notebook<\/strong>? The Jupyter <strong>Notebook<\/strong> is a web-based interactive computing platform. The notebook combines live <strong>code<\/strong>, equations, narrative text, visualizations, interactive dashboards and other media. On the other hand, Apache Zeppelin is detailed as &#8220;A web-based notebook that enables interactive data analytics&#8221;.<\/p>\n<p>Also the question is, how do I reset my Zeppelin interpreter? You can restart the interpreter for the notebook in the interpreter bindings (gear in upper right hand corner) by clicking on the restart icon to the left of the interpreter in question (in this case it would be the spark interpreter).<\/p>\n<p>Amazingly, where are Zeppelin notebooks stored? This notebook authorization file (notebook-authorization. json) is located in the \/usr\/lib\/zeppelin\/conf directory.<\/p>\n<p>Also know, how do you use Zeppelin <strong>notebook<\/strong>? <iframe style=\"margin-top:25px;width:100%;height:420px;\" width=\"auto\" height=\"auto\" src=\"https:\/\/www.youtube.com\/embed\/CfhYFqNyjGc\"><\/iframe>Both notebooks have markdown support but unlike Jupyter, Zeppelin creates interactive forms and the visualisation results in a faster way. Also, the result is more accurate and easily accessible to the end users.<\/p>\n<h2>Which is an advantage that Zeppelin holds over other notebook?<\/h2>\n<\/p>\n<p>Appearance. Both UIs are similar, but Zeppelin&#8217;s biggest advantage is that it allows the combination of multiple paragraphs into one line. It also has a built-in simple data visualisation tool for some interpreters and a table output that allows sorting out-of-the-box.<\/p>\n<\/p>\n<h2>How do I reset my Zeppelin EMR?<\/h2>\n<\/p>\n<ol>\n<li>Connect to the master node using SSH.<\/li>\n<li>List all running services: ls \/etc\/init.d\/<\/li>\n<li>Run the following command to restart the service. Replace &#8220;hadoop-hdfs-namenode&#8221; with the service that you want to restart.  <\/li>\n<li>Verify that the process is running:<\/li>\n<\/ol>\n<\/p>\n<h2>Does Zeppelin use Livy?<\/h2>\n<\/p>\n<p>Starting from livy 0.5 which is supported by Zeppelin 0.8. 0, SparkContext is shared between scala, python, r and sql.<\/p>\n<\/p>\n<h2>How do I install Zeppelin on Windows 10?<\/h2>\n<\/p>\n<ol>\n<li>Prerequisites. Follow either of the following pages to install WSL in a system or non-system drive on your Windows 10.  <\/li>\n<li>Download binary package.  <\/li>\n<li>Unzip the binary package.  <\/li>\n<li>Start Zeppelin service.  <\/li>\n<li>Open Zeppelin portal.  <\/li>\n<li>Stop Zeppelin service.<\/li>\n<\/ol>\n<\/p>\n<h2>How do I know what version of Zeppelin I have?<\/h2>\n<\/p>\n<ol>\n<li>Locate the build.version file at notebook_deployment_dir \/Zeppelin- version \/zeppelin- version -incubating-bin-spark- version _hadoop- version \/.  <\/li>\n<li>Open the build.version file and look for the build date and number.<\/li>\n<\/ol>\n<\/p>\n<h2>What is a Zeppelin notebook?<\/h2>\n<\/p>\n<p>A completely open web-based notebook that enables interactive data analytics. Apache Zeppelin is a new and incubating multi-purposed web-based notebook which brings data ingestion, data exploration, visualization, sharing and collaboration features to Hadoop and Spark.<\/p>\n<\/p>\n<h2>How do you load data into a Zeppelin?<\/h2>\n<\/p>\n<ol>\n<li>Use &#8216;wget&#8217; through %sh in Zeppelin. The data file should be uploaded to somewhere on the internet and have a http or https URL for accessing it.  <\/li>\n<li>Drag\/Drop files in iPython notebook.<\/li>\n<\/ol>\n<\/p>\n<h2>How does Apache Zeppelin work?<\/h2>\n<\/p>\n<p>Collaborate by sharing your Notebook &#038; Paragraph Then Apache Zeppelin will broadcast any changes in realtime, just like the collaboration in Google docs. Apache Zeppelin provides an URL to display the result only, that page does not include any menus and buttons inside of notebooks.<\/p>\n<\/p>\n<h2>How do I use python Zeppelin?<\/h2>\n<\/p>\n<ol>\n<li>Configuration. Property.  <\/li>\n<li>Enabling Python Interpreter. In a notebook, to enable the Python interpreter, click on the Gear icon and select Python.<\/li>\n<li>Using the Python Interpreter.  <\/li>\n<li>Python modules.  <\/li>\n<li>Use Zeppelin Dynamic Forms.  <\/li>\n<li>Zeppelin features not fully supported by the Python Interpreter.  <\/li>\n<li>Matplotlib integration.  <\/li>\n<li>Pandas integration.<\/li>\n<\/ol>\n<\/p>\n<h2>What were Jupyter notebooks called before the name was changed to Jupyter?<\/h2>\n<\/p>\n<p>Jupyter Notebook (formerly IPython Notebooks) is a web-based interactive computational environment for creating notebook documents.<\/p>\n<\/p>\n<h2>Is Jupyter notebook fast?<\/h2>\n<\/p>\n<p>I have found that Jupyter is significantly slower than Ipython, whether or not many print statements are used. Nearly all functions suffer decreased performance, but especially if you are analyzing large dataframes or performing complex calculations, I would stick with Ipython.<\/p>\n<\/p>\n<h2>Does Databricks use Jupyter notebook?<\/h2>\n<\/p>\n<p>Does Databricks offer support for Jupyter Notebooks? Yes. Databricks clusters can be configured to use the IPython kernel in order to take advantage of the Jupyter ecosystem&#8217;s open source tooling (display and output tools, for example).<\/p>\n<\/p>\n<h2>What is a spark notebook?<\/h2>\n<\/p>\n<p>The Spark Notebook is the open source notebook aimed at enterprise environments, providing Data Scientists and Data Engineers with an interactive web-based editor that can combine Scala code, SQL queries, Markup and JavaScript in a collaborative manner to explore, analyse and learn from massive data sets.<\/p>\n<\/p>\n<h2>What is Zeppelin tool used for?<\/h2>\n<\/p>\n<p>Apache Zeppelin takes the idea of a notebook, or interactive shell for Spark, up an order of magnitude. It is quite a sophisticated tool for creating visualizations, reports, etc. from Spark or Hive and then sharing those as live reports for users and output reports and graphs as formatted web pages.<\/p>\n<\/p>\n<h2>Which of the following is an interpreter built into Apache Zeppelin?<\/h2>\n<\/p>\n<p>Currently, Zeppelin supports many interpreters such as Scala ( with Apache Spark ), Python ( with Apache Spark ), Spark SQL, JDBC, Markdown, Shell and so on.<\/p>\n<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the commits dropdown (see image) you can probably select a previous commit to return to that version.
