Scenario

After an HBase application is run, you can check the running result through one of the following methods:

• Viewing the IntelliJ IDEA running result.
• Viewing HBase logs.
• Logging in to the HBase WebUI, see More Information > External Interfaces > WebUI.
• Using HBase Shell command, see More Information > External Interfaces > Shell.

Procedure

• After the hbase-sample is successfully executed, the following information is displayed:

• Log description

  The log level is INFO by default and more detailed information can be viewed by changing the log level (DEBUG, INFO, WARN, ERROR, and FATL). You can modify the log4j.properties file to change log levels, for example:

  hbase.root.logger=INFO,console
  ...
  log4j.logger.org.apache.zookeeper=INFO
  #log4j.logger.org.apache.hadoop.fs.FSNamesystem=DEBUG
  log4j.logger.org.apache.hadoop.hbase=INFO
  # Make these two classes DEBUG-level. Make them DEBUG to see more zk debug.
  log4j.logger.org.apache.hadoop.hbase.zookeeper.ZKUtil=INFO
  log4j.logger.org.apache.hadoop.hbase.zookeeper.ZooKeeperWatcher=INFO
  ...
