Saving Data to HIVE¶
As par of your data pipeline or workflow, you might want to save data to HIVE after it has been read from a data source, cleaned and transformed. After data is saved in HIVE it can be read from another workflow or accessed through BI tools such as Tableau.
Cluster vs Standalone Mode¶
In your workflow, drag and drop a “SaveAsHIVETable” processor. Configure the processor to save your data into HIVE as a table which can be read later.
Note: Fire Insights can run in cluster mode or in the standalone mode. These settings are in Administration/Configuration.When connecting to HIVE, Sparkflows must be running in cluster mode on an edge node of a Hadoop cluster. HIVE settings have to be correctly set under Administration/Configuration-> app.runOnCluster.
The example workflow below, contains “SaveAsHIVETable” processor. It reads Housing dataset and saves it into the HIVE ‘housing_table’.
When the example workflow is executed, data is written into HIVE table ‘housing_table’.
The ‘housing_table’ gets created with the schema of the Housing Dataset.
