想知道您是否可以在查询 geomesa/Accumulo 时帮助我们理解一个问题？

问题：

  1. 当我们用它查询所有字段时，geomesa export -u A -p B -c catalog1 -f d1-json -F csv它会返回数据（请参见下面的示例）。

  2. -a "short_text_field"当我们使用OR 甚至是简单的列添加子集时，-q "short_text_field='Cow'"尽管存在数据，它仍返回 0 个特征： geomesa export -u A -p B -c catalog1 -f d1-json -F csv -a "short_text_field" INFO Exported 0 features id,short_text_field:String,*geom:Point:srid=4326 INFO Feature export complete to standard out in 2077ms

(1) 中的样本数据：

id,geom:Point:srid=4326,short_text_field:String,long_text_field_1:String,long_text_field_2:String e9c756ef-06d6-42dd-84a9-c774ec9086ec,POINT (-117.830256 -76.799443),597Fish,”牛车？牛鱼老鼠猫车Fish Horse Mouse Fish”，“诶诶迪伊迎迎益伊迎迎诶迎伊”）

问题：有人知道调试这个的最佳方法吗？

使用 -a 运行查询时的日志摘录：

解决方案是简单地将命名空间作为前缀添加到摄取和导出命令目录参数。

摄取时请务必指定 namespace.catalogname

同样，查询时也必须这样做。
