无法在Geomesa功能类型中使用两个属性索引查询

Question

我正在查询一个Geomesa功能，其中包括两个属性上的join索引(r和di(。查询r=<int-value>运行并返回数据以确定的r值(如果有(。但是，查询di=<int-value>尽管存在相同的记录，但找不到任何匹配记录！

这是我的功能模式：

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一个以上的属性索引吗？

我通过在Maven Shade插件中添加缺失的变压器来选择各种运行时实现，从而解决了此问题。
