NOTE:

In the Windows environment, the following exception occurs but does not affect services.

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
