1. The tables and data in the following relational databases are required to be converted into tables suitable for HBase storage and inserted into the data:
Student table (Student) (excluding the last column)
Student ID (S_No) |
Name (S_Name) |
Gender (S_Sex) |
Age (S_Age) |
course |
2015001 |
Zhangsan |
male |
23 |
|
2015003 |
Mary |
female |
22 |
|
2015003 |
Lysis |
male |
24 |
Math 85 |
2. Use the HBase Shell commands provided by Hadoop to accomplish the same task:
- List information about all HBase tables; list
- Print out all the recorded data of the student table in the terminal;
- Add a course column family to the student table;
- Add a math column to the course column family and register a grade of 85;
- delete the course column;
- The number of rows in the statistics table; count 's1'
- Clear all record data of the specified table; truncate 's1'
