Clear Analytics でHive Data に連携するグラフを作成

Clear Analytics でHive data に連携したダイナミックチャートを作成し、分析を実施。

CData ODBC Driver for Hive を使えば、Hive に標準ODBC でのアクセスが可能になり、いろいろなBI、レポーティング、ETL ツールからデータ連携が可能になります。本記事では、Microsoft Excel のアドインであるClear Analytics からHive データにODBC データソースとして接続し、クエリ、テーブル、チャート、ピボットテーブルを作成する方法を説明します。

Hive Data への連携


ODBC Data Source Name の設定

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

Apache Hive への接続を確立するには以下を指定します。

  • Server:HiveServer2 をホストするサーバーのホスト名またはIP アドレスに設定。
  • Port:HiveServer2 インスタンスへの接続用のポートに設定。
  • TransportMode:Hive サーバーとの通信に使用するトランスポートモード。有効な入力値は、BINARY およびHTTP です。デフォルトではBINARY が選択されます。
  • AuthScheme:使用される認証スキーム。有効な入力値はPLAIN、LDAP、NOSASL、およびKERBEROS です。デフォルトではPLAIN が選択されます。
  • 本製品 においてTLS/SSL を有効化するには、UseSSL をTrue に設定します

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Clear Analytics でのデータソース設定

  1. Open Excel and navigate to the CLEAR ANALYTICS ribbon. Once there, open the Data Manager.
  2. Select Database as the data source.
  3. In the Set Connection section, click the option to create a new database.
  4. Select Microsoft ODBC Data Source as the data source and click OK.
  5. Select the DSN you already configured from the drop-down menu.
  6. Back on the Set Connection section, select Standard (ANSI ODBC) Query Builder as the SQL Builder Provider and click Next.
  7. Select the Schema/Owner and choose the domains (tables) that you wish to use in Clear Analytics.
  8. Prepare your data objects as needed by customizing the display names and descriptions of the tables and columns.
  9. For the vast majority of the CData ODBC Drivers, you will not set a key date for your domains.
  10. In the Domain Relations section, add any relational information between tables.
  11. In the Domain Tree section, create groups for your data and add the available items to the groups.
  12. Review the summary of your data and click Finish.

Hive Data のグラフ作成

You are now ready to create a chart with Hive data.

Create a New Query

  1. Click Repository in the CLEAR ANALYTICS ribbon.
  2. Create a new query.
  3. Select the columns you wish to retrieve.
  4. Set the aggregation type for your data (use the blank entry if you do not wish to aggregate the data).
  5. Set filters and formulas by dragging columns to the lower window.
  6. Name your query and click Save.

BQuery Report のグラフ作成

With the query created, you are now ready to execute a report and display a chart.
  1. Click Report Explorer in the CLEAR ANALYTICS ribbon.
  2. In the Report Explorer pane, click the 'New Report' icon in the toolbar.
  3. Select the query you just created.
  4. Name the report and click 'Save and Execute'.
  5. Click the Results tab within the Report Explorer
  6. Expand your report and drag the chart to the Excel spreadsheet.
  7. In the resulting PivotChart window, drag the fields (columns) to the Filters, Legends, Axis (Categories), and Values windows.

With a new data source in Clear Analytics established and a chart created, you are ready to begin analysis of Hive data. With the ODBC Driver for Hive and Clear Analytics, you can perform self-service analytics in Excel with live data, directly from Hive.
