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.

HBase/Phoenix对接SpringBoot运行结果
 在浏览器上访问链接“http://样例运行节点IP地址:8080/hbase/HBaseDemo”和“http://样例运行节点IP地址:8080/hbase/PhoenixDemo”，IDEA正常打印日志，请求返回“finish HBase”和“finish Phoenix"，如下图所示：

图1 返回“finish HBase”

图2 返回“finish Phoenix"

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
...
