Problem 7. Basics for Pig, Hive, and HBase

(HBase) Previously, in Hadoop, we used start-dfs.sh and start-yarn.sh commands to start HDFS and YARN services. In HBase, what is the command to start HBase service?

Answer:

This file is in which directory?

Answer:

After we start the HBase service, we can start the HBase shell. Please provide the command to start the HBase shell?

Answer:

Suppose we already have a table workers. The workers information has been put into this table. Rob wants to view all the information. Which command should Rob type in the shell in order to see all the workers information in the table workers?

Answer:

If we program a CountWorkers.java source code file for using HBase to count the workers, how should we run this HBase program? Rob figures out we need to first compile it into a runnable CountWorkers.jar file. Then what is the command to run this CountWorkers.jar file?
