MapReduce服务 MRS

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=DEBUGlog4j.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=INFOlog4j.logger.org.apache.hadoop.hbase.zookeeper.ZooKeeperWatcher=INFO...
