Here we have listed a few ETL tools both, traditional and Open source you can have a look at them and see for yourself which one suits your use case. 1. Panoply: Panoply is the main cloud ETL supplier and data warehouse blend. With 100+ data connectors, ETL and data ingestion is quick and simple, with only a couple of snaps and a login among you and your recently coordinated data. In the engine, Panoply is really utilizing an ELT approach (instead of conventional ETL), which makes data ingestion a lot quicker and progressively powerful, since you don't need to trust that change will finish before stacking your data. What's more, since Panoply fabricates oversaw cloud data warehouses for each client, you won't have to set up a different goal to store all the data you pull in utilizing Panoply's ELT procedure. On the off chance that you'd preferably utilize Panoply's rich arrangement of data gatherers to set up ETL pipelines into a current data warehouse, Panoply can likewise oversee ETL forms for your Azure SQL Data Warehouse. 2. Stitch: Stitch is a self-administration ETL data pipeline. The Stitch API can reproduce data from any source, and handle mass and gradual data refreshes. Stitch additionally gives a replication motor that depends on various techniques to convey data to clients. Its REST API underpins JSON or travel, which empowers programmed recognition and standardization of settled report structures into social constructions. Stitch can associate with Amazon Redshift engineering, Google BigQuery design, and Postgres design - and incorporates with BI apparatuses. Stitch is normally intended to gather, change and burden Google examination data into its own framework, to naturally give business bits of knowledge on crude data. 3. Sprinkle: Sprinkle is a SaaS platform providing ETL tool for organisations.Their easy to use UX and code free mode of operations makes it easy for technical and non technical users to ingest data from multiple data sources and drive real time insights on the data. Their Free Trial enables users to first try the platform and then pay if it fulfils the requirement. Some of the open source tools include 1. Heka: Heka is an open source programming framework for elite data gathering, investigation, observing and detailing. Its principle part is a daemon program known as 'hekad' that empowers the usefulness of social occasion, changing over, assessing, preparing and conveying data. Heka is written in the 'Go' programming language, and has worked in modules for contributing, disentangling, separating, encoding and yielding data. These modules have various functionalities and can be utilized together to assemble a total pipeline. Heka utilizes Advanced Message Queuing Protocol (AMQP) or TCP to transport data starting with one area then onto the next. It tends to be utilized to stack and parse log records from a document framework, or to perform constant investigation, charting and inconsistency recognition on a data stream. 2. Logstash: Logstash is an open source data handling pipeline that ingests data from numerous sources at the same time, changing the source data and store occasions into ElasticSearch as a matter of course. Logstash is a piece of an ELK stack. The E represents Elasticsearch, a JSON-based hunt and investigation motor, and the K represents Kibana, which empowers data perception. Logstash is written in Ruby and gives a JSON-like structure which has a reasonable division between inner items. It has a pluggable structure highlighting more than 200 modules, empowering the capacity to blend, coordinate and arrange offices over various information, channels and yield. This instrument can be utilized for BI, or in data warehouses with bring, change and putting away occasion capacities. 3. Singer: Singer's open source, order line ETL instrument permits clients to assemble measured ETL pipelines utilizing its "tap" and "target" modules. Rather than building a solitary, static ETL pipeline, Singer gives a spine that permits clients to interface data sources to capacity goals. With a huge assortment of pre-constructed taps, the contents that gather datapoints from their unique sources, and a broad choice of pre-fabricated focuses on, the contents that change and burden data into pre-determined goals, Singer permits clients to compose succinct, single-line ETL forms that can be adjusted on the fly by trading taps and focuses in and out.

@Graham Martin Thanks for your reply, I thihk I haved already define the Tag Service and add it to the hive policy In the tag service I give user "admin" the permission to select all the tables/columns under the tag "Hive", and in Hive Policy I disable the user "admin" 's permission to select of all tables, so if the tag service works, "admin" should have the permission to visit all tables under the tag "Hive", but currently it is not working. Am I missing something here?

@Christophe Vico I recommend you download the Sandbox: https://hortonworks.com/products/sandbox/ From Zeppelin, and in the one notebook, you can run different versions of Spark (1.6.3 or 2.1) as per your choice of interpreter: %spark.spark or %spark2.spark You can review the settings used in the Interpreter screen.

Hi @christophe menichetti, As @Predrag Monodic mentioned, you can use Blueprints for non-UI based installs. Unfortunately, the UI Wizard will not allow you to generate a Blueprint and Cluster Creation template after you gone through all the screens. The simplest way to generate a Blueprint to start with is to try the following: 1. On a local VM cluster for testing (vagrant, docker, etc), create a cluster that has the services, components, and configuration that you are interested in deploying in your production cluster. 2. Use the UI to deploy this local cluster, going through all the normal screens in the wizard. 3. You can then export the Blueprint from this running cluster. This REST call will generate a Blueprint based on the currently-running cluster you setup in Step #2. 4. Save this Blueprint, and customize it as necessary. 5. Create a Cluster Creation Template that matches hostnames to the host groups from the exported Blueprint. Please note that you may want to manually rename the host groups in the exported Blueprint, as they are generated using a "host_group_n" convention, which may not be useful for documenting your particular cluster. You can check out the following link on the Blueprints wiki to see how to make the REST call to export the Blueprint from a running cluster: https://cwiki.apache.org/confluence/display/AMBARI/Blueprints#Blueprints-APIResourcesandSyntax Hope this helps!

@nedox nedox You will want to use one of the available HDFS processors to get data form your HDP HDFS file system.
1. GetHDFS <-- Use if standalone NiFi installation
2. ListHDFS --> RPG --> FetchHDFS <-- Use if NiFI cluster installation
All of the HDFS based NiFi processors have a property that allows you to specify a path to the HDFS site.xml files. Obtain a copy of your core-site.xml and hdfs-site.xml files from your HDP cluster and place them somewhere on the HDF hosts running NiFi. Point to these files using the "Hadoop Configuration Resources" processor property. example: Thanks, Matt
