Insert a table record using Hbase Hue
Category : Hadoop | Sub Category : Apache HBase | By Prasad Bonam Last updated: 2020-10-17 08:15:07 Viewed : 810
Insert a table record using HBase Hue
Click on ‘New Row’ to insert new row
Click on `Add Field` button
Row Key:
Rowkeys cannot be changed. The only way they can be
"changed" in a table is if the row is deleted and then re-inserted.
HBase data stores consist of one or
more tables, which are indexed by row keys. Data is stored in rows with
columns, and rows can have multiple versions. By default, data versioning for
rows is implemented with time stamps.
Syntax of Row Key : Column Family: {Column
Qualifier:Version:Value}
Insert new Row
Row Key
1:Ram
Column
Families
Cf:empId 1
Cf:empName Ram
Cf:salary 1000

- You are building an Azure Stream Analytics pipeline. You need to configure the pipeline to analyze events that occur during a five-minute window after an event fires. Which windowing function should you use?
- You create an Azure Stream Analytics job. You run the job for five hours. You need to ensure that these events are not dropped. What should you do?
- You design an Azure Data Factory data flow activity to move large amounts of data from text files to an Azure Synapse Analytics database. You add a data flow script to your data flow. The data flow in the designer has the following tasks: distinctRows1: Aggregate data by using myCols that produce columns. source1: Import data from DelimitedText1. derivedColumn1: Create and update the C1 columns. select1: Rename derivedColumn1 as select1 with columns C1. sink1: Add a sink dataset. You need to ensure that all the rows in source1 are deduplicated. What should you do?
