查看Windows调测结果
操作场景
HBase应用程序运行完成后,可通过如下方式查看运行情况。
- 通过IntelliJ IDEA运行结果查看应用程序运行情况。
- 通过HBase日志获取应用程序运行情况。
- 登录HBase WebUI查看应用程序运行情况。可参见 。
- 通过HBase shell命令查看应用程序运行情况。可参见 。
操作步骤
- hbase-example样例运行成功后,显示信息如下:

在Windows环境运行样例代码时会出现下面的异常,但是不影响业务:
java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries.
- 日志说明
日志级别默认为INFO,可以通过调整日志打印级别(DEBUG,INFO,WARN,ERROR,FATL)来显示更详细的信息。可以通过修改“log4j.properties”文件来实现,如:
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 ...
