-## Data Importer
|
|
|
-
|
|
|
-The goal of the importer is to allow ad hoc queries on data not yet in the clusters thereby expedite self-service analytics.
|
|
|
-
|
|
|
-If you want to import your own data instead of installing the sample
|
|
|
-tables, open the importer from the left menu or from the little `+` in the left assist.
|
|
|
-
|
|
|
-If you've ever struggled with creating new SQL tables from files, you'll be happy to learn that this is now much easier. The wizard has been revamped to two simple steps and also offers more formats. Now users just need to:
|
|
|
-
|
|
|
-1. Select a source type
|
|
|
-2. Select the type of object for the destination
|
|
|
-
|
|
|
-And that's it!
|
|
|
-

## SQL Tables
|

|
|
- steps are:
|
|
|
- - Name the table.
|
|
|
- - Choose the record format.
|
|
|
- - Configure record serialization by specifying delimiters for
|
|
|
- columns, collections, and map keys.
|
|
|
- - Choose the file format.
|
|
|
- - Specify the location for your table's data.
|
|
|
- - Specify the columns, providing a name and selecting the type for
|
|
|
- each column.
|
|
|
- - Specify partition columns, providing a name and selecting the

-## Indexing
|
|
|
-
|
|
|
-In the past, indexing data into Solr to then explore it with a [Dynamic Dashboard](http://gethue.com/search-dashboards/) has been quite difficult. The task involved writing a Solr schema and a Morphlines file then submitting a job to YARN to do the indexing. Often times getting this correct for non trivial imports could take a few days of work. Now with Hue's new feature you can start your YARN indexing job in minutes. This tutorial offers a step by step guide on how to do it.

|
|
-Any CSV file can be dragged & dropped and ingested into an index in a few clicks via the Data Import Wizard [link]. The indexed data is immediately queryable and its facets/dimensions will be very fast to explore.

|
|
|
-### Browsing
|
|
|
-
|
|
|
-The Collection browser got polished in the last releases and provide more information on the columns. The left metadata assist of Hue 4 makes it handy to list them and peak at their content via the sample popup.

|
|
|
-Hue's Metastore Import Data Wizard can create external Hive tables directly from data directories in S3. This allows S3 data to be queried via SQL from Hive or Impala, without moving or copying the data into HDFS or the Hive Warehouse.
|
|
|
-
|
|
|
-To create an external Hive table from S3, navigate to the Metastore app, select the desired database and then click the “Create a new table from a file” icon in the upper right.
|
|
|
-
|
|
|
-Enter the table name and optional description, and in the “Input File or Directory” filepicker, select the S3A filesystem and navigate to the parent directory containing the desired data files and click the “Select this folder” button. The “Load Data” dropdown should automatically select the “Create External Table” option which indicates that this table will directly reference an external data directory.
|
|
|
-
|
|
|
-Choose your input files' delimiter and column definition options and finally click “Create Table” when you're ready to create the Hive table. Once created, you should see the newly created table details in the Metastore.

-
|
|
|
-**Save Query Results to S3**

-

-Now that we have created external Hive tables created from our S3 data, we can jump into either the Hive or Impala editor and start querying the data directly from S3 seamlessly. These queries can join tables and objects that are backed either by S3, HDFS, or both. Query results can then easily be saved back to S3.

From here, we can view the existing keys (both directories and files) and create, rename, move, copy, or delete existing directories and files. Additionally, we can directly upload files to ADLS.

To create an external Hive table from ADLS, navigate to the table browser, select the desired database and then click the plus icon in the upper right. Select a file using the file picker and browse to a file on ADLS.

-Now that we have created external Hive tables created from our ADLS data, we can jump into either the Hive or Impala editor and start querying the data directly from ADLS seamlessly.
