MAPREDUCE服务 MRS 在Windows中调测程序

操作步骤

运行结果会有如下成功信息：

2016-07-13 14:36:12,736 INFO  [main] basic.CreateTableSample: Create table sampleNameSpace:sampleTable successful!
2016-07-13 14:36:15,426 INFO  [main] basic.ModifyTableSample: Modify table sampleNameSpace:sampleTable successfully.
2016-07-13 14:36:16,708 INFO  [main] basic.MultiSplitSample: Mmulti split table sampleNameSpace:sampleTable successfully.
2016-07-13 14:36:17,299 INFO  [main] basic.PutDataSample: Successfully put 9 items data into sampleNameSpace:sampleTable.
2016-07-13 14:36:18,992 INFO  [main] basic.ScanSample: Scan data successfully.
2016-07-13 14:36:20,532 INFO  [main] basic.DeletaDataSample: Successfully delete data from table sampleNameSpace:sampleTable.
2016-07-13 14:36:21,006 INFO  [main] acl.AclSample: Grant ACL for table sampleNameSpace:sampleTable successfully.
2016-07-13 14:36:27,836 INFO  [main] index.CreateIndexSample: Successfully add index for table sampleNameSpace:sampleTable.

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
...
