想知道您是否可以帮助我们了解查询几何台面/累积时的问题？
问题：
-
当我们使用
geomesa export -u A -p B -c catalog1 -f d1-json -F csv查询所有字段时，它会返回数据（请参阅下面的示例）。 -
当我们添加带有
-a "short_text_field"OR 甚至简单-q "short_text_field='Cow'"的列子集时，尽管存在数据，但它仍返回 0 个特征：geomesa export -u A -p B -c catalog1 -f d1-json -F csv -a "short_text_field"信息 导出的 0 个要素id，short_text_field：字符串，*geom：Point：srid=4326信息功能导出在2077ms内完成到标准输出
来自 （1） 的示例数据：
id，geom：Point：srid=4326，short_text_field：String，long_text_field_1：String，long_text_field_2：Stringe9c756ef-06d6-42dd-84a9-c774ec9086ec，POINT （-117.830256 -76.799443），597鱼，"牛车？牛鱼老鼠猫车鱼马鼠鱼"，"诶 迪伊 迎益 伊 迎 诶 迎 诶 伊"）
问题：有没有人知道调试它的最佳方法？

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，请确保指定命名空间.目录名称
同样，查询时也必须执行相同的操作。
