儘管存在數據，但Geomesa導出仍然無結果

Question

想知道在查詢geomesa/Accumulo時是否可以幫助我們理解問題？

問題：

1. 當我們查詢與geomesa export -u A -p B -c catalog1 -f d1-json -F csv所有領域，它返回的數據（參見下面的示例）。

2. 當我們添加列的一個子集-a "short_text_field"甚至一個簡單的-q "short_text_field='Cow'"返回0功能，儘管數據存在： geomesa export -u A -p B -c catalog1 -f d1-json -F csv -a "short_text_field" 信息導出0的功能 ID，short_text_field：字符串，* GEOM：點：SRID = 4326 INFO特徵出口完整標準輸出在從（1）2077ms

樣本數據：

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，「Cow Car？牛魚妙妙貓汽車魚馬鼠魚「」誒迪伊迎益伊迎誒迎誒伊「）

Answer 1

的解決方案是簡單地將命名空間的前綴採集和導出命令目錄參數

當攝取一定要指定namespace.catalogname

類似地，查詢時必須做同樣的事情。
