HBase Mock Test III
Q 1 - If we choose the rowkey to be a timestamp then inserting data to such a Hbase table will be
If the rowkey is made as timestamp then it will always be written to a specific region and at the end of the table, overloading just one machine holding that region. SO it will be slower than other type of rowkey.
Q 2 - Which of the following pair is an option for effectively distributing the data across multiple regions?
Hashing the rowkeys gives randomly distributed values and salting involves adding a random number to the rowkey. Both these options create a good distribution of keys to be used across multiple regions.
The toe predefined namespace in Hbase are – habse and default. Habse contains internal tables and default contains the tables which are not qualified with any namespace.
Q 8 - Which of the following is declared during the schema definition creation?
The column families are declared upfront during the schema definition creation. But the column names can be declared anytime when the Table is up and running.
Q 9 - The tuple which specifies a cell in Hbase is
When a counter is initialized, its value depends on what is specified during its creation. Only if no specific value is mentioned it will initialize to zero.
Q 25 - You can process an arbitrary code on a region server using
