hive集成hbase异常

hive集成hbase之后，查询出现以下异常，则说明对应的jar包没有指定：

 
  
  
  
  

  
   
   
   
   
Error: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.mapreduce.TableSplit
  
   
   
   
   
Error: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.client.HTable
  
   
   
   
   
Error: java.io.IOException: java.io.IOException: java.lang.reflect.InvocationTargetException Caused by: java.lang.ClassNotFoundException: org.cloudera.htrace.Traceat java.net.URLClassLoader$1.run(URLClassLoader.java:366)
  
   
   
   
   
Error: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.protobuf.generated.MasterProtos$MasterService$BlockingInterface
 
  
  
  
  

解决方法：需要在hive/conf/hive-site.xml中指定jar包路径。

<property> <name>hive.aux.jars.path</name> <value>file:///usr/lib/gphd/hbase/lib/hbase-server.jar,file:///usr/lib/gphd/hbase/lib/hbase-client.jar,file:///usr/lib/gphd/hbase/lib/hbase-protocol.jar,file:///usr/lib/gphd/hbase/lib/htrace-core-2.01.jar</value> </property>

以下是抛出的错误类对应的jar包

Class Name	Jar Name
TableSplit	hbase-server.jar
HTable	hbase-client.jar
MasterProtos	hbase-protocol.jar
org.cloudera.htrace.Trace	htrace-core-2.01.jar
