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。

操作步骤

• hbase-example样例运行成功后，显示信息如下：

  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.

• 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
  ...
