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“更多信息 > 对外接口 > Web UI ”。
• 通过HBase shell命令查看应用程序运行情况。可参见“更多信息 > 对外接口 > Shell ”。

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
  ...
