Later I found spring-data-hadoop has a dependency with spring-data-hadoop-hbase, which has
dependency with hbase-client, but with version 0.98.5, so I switch to 


 
<dependency>
 
		<groupId>org.springframework.data</groupId>
 
		<artifactId>spring-data-hadoop</artifactId>
 
		<version>2.1.2.RELEASE</version>
 
	</dependency>
 


 
	
 
	
 
		<!-- 	 -->
 
	<dependency>
 
		<groupId>org.apache.hbase</groupId>
 
		<artifactId>hbase-client</artifactId>
 
		<version>0.98.5-hadoop2</version>
 
	</dependency> 




But still come to the same problem.

Subject:  Simple HbaseTemplate demo can't run



Hi,



I am running HDP2.2 with Hbase 0.98.4.2.2.0.0 and HDFS 2.6.0.2.2.0.0, so I add the 2.1.2.RELEASE
version of spring-data-hadoop to my maven pom file, but failed to complie with the following
error messages:




Exception in thread "main" java.lang.Error: Unresolved compilation problems: 

	The type org.apache.hadoop.hbase.client.Scan cannot be resolved. It is indirectly referenced
from required .class files

	The type new RowMapper<String>(){} must implement the inherited abstract method RowMapper<String>.mapRow(Result,
int)

	Result cannot be resolved to a type

at bh.com.hbase_test.HBaseSpringTest.main(HBaseSpringTest.java:23)

I thought spring-data-hadoop should has hbase-client as it's dependency, but I found it does
not, so I add the 0.98.4-hadoop2 version of hbase-client manually, then the program can compile,
but failed with the following
