Geomesa 导出 returns 尽管存在数据但没有结果

Question

想知道您是否可以帮助我们理解查询时的问题 geomesa/Accumulo？

问题：

当我们用geomesa export -u A -p B -c catalog1 -f d1-json -F csv查询所有字段时它returns数据（见下面的示例）。
当我们添加带有 -a "short_text_field" 或什至是简单的 -q "short_text_field='Cow'" 的列的子集时，尽管存在数据，它仍具有 returns 0 个特征： geomesa export -u A -p B -c catalog1 -f d1-json -F csv -a "short_text_field" INFO 导出 0 个特征 id,short_text_field:String,*geom:Point:srid=4326 INFO 功能导出在 2077 毫秒内完成到标准输出

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:String e9c756ef-06d6-42dd-84a9-c774ec9086ec,POINT (-117.830256 -76.799443),597Fish,"牛车?牛鱼鼠猫车鱼马鼠鱼","请迪伊迎益伊迎请迎请伊")

问题：有人知道调试这个的最佳方法吗？

解决方案是简单地将命名空间添加为摄取和导出命令目录参数的前缀。

摄取时务必指定 namespace.catalogname

同样查询的时候也要做同样的事情

Geomesa 导出 returns 尽管存在数据但没有结果

Geomesa export returns no results despite data being present

geospatial

cql

accumulo
