我正在查询一个 geomesa 功能，其中包括join两个属性（r和di）的索引。查询r=<int-value>运行并返回指定r值的数据（如果有）。但是，尽管存在相同的记录，但 Querydi=<int-value>没有找到任何匹配的记录！

这是我的功能架构：

r:Long:cardinality=high:index=join,*g:Point:srid=4326,di:Integer:index=join,al:Float,s:Float,b:Float,an:Float,he:Float,ve:Float,t:Float,m:Boolean,i:Boolean,ts:Long;geomesa.table.sharing='true',geomesa.indices='attr:4:3,records:2:3,z2:3:3',geomesa.table.sharing.prefix='\\u0001'

我无法找出根本原因。我不能在一个模式中有多个属性索引吗？

我通过在 maven shade 插件中添加缺少的转换器来选择各种运行时实现来解决这个问题，如下所示

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-shade-plugin</artifactId>
   <version>3.0.0</version>
   <executions>
      <execution>
         <phase>package</phase>
         <goals>
            <goal>shade</goal>
         </goals>
         <configuration>
            <!-- <minimizeJar>true</minimizeJar> -->
            <createDependencyReducedPom>false</createDependencyReducedPom>
            <filters>
               <filter>
                  <artifact>*:*</artifact>

                     <exclude>META-INF/*.RSA</exclude>
                  </excludes>
               </filter>
            </filters>
            <transformers>
