HBase/Spark Guava依赖冲突解决方案

前言

版本guava 版本
Spark2.2.012.0.1
HBase1.0.0-cdh5.6.020.0

由于guava的版本在16.0以后，不向后兼容，所以Spark程序中集成HBase是会报找不到依赖的方法错误， 如下：

Caused by: org.apache.hadoop.hbase.DoNotRetryIOException: java.lang.IllegalAccessError: tried to access method com.google.common.base.Stopwatch.<init>()V from class org.apache.hadoop.hbase.zookeeper.MetaTableLocator

    at org.springframework.data.hadoop.hbase.HbaseTemplate.execute(HbaseTemplate.java:61)
    ... 75 more

解决方案

使用 maven-shade-plugin 打包hbase依赖，把依赖的包打包进项目，并且修改依赖包的包名，这样hbase引用的就是修改包名后的guava包了，不在依赖原生的guava包。

                        </goals>

                </executions>
                <configuration>
                    <filters>
                        <filter>

                            <excludes>
                                <exclude>META-INF/*.SF</exclude>
                                <exclude>META-INF/*.DSA</exclude>
                                <exclude>META-INF/*.RSA</exclude>
                            </excludes>
                        </filter>
                    </filters>
                    <!-- Additional configuration. -->
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

然后，spark集成hbase时，引用maven-shade-plugin打包后的hbase包，冲突解决。

 <dependency>
     <groupId>com.xxx.xxx.xxx</groupId>
     <artifactId>your-hbase</artifactId>
     <version>1.0.0</version>
 </dependency>
