尽管存在数据，Geomesa导出仍然没有返回结果

想知道您是否可以在查询geomesa / Accumulo时帮助我们了解问题？

问题：

  1. 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）。

  2. 当我们添加-a "short_text_field"或甚至简单-q "short_text_field='Cow'"的列子集时，尽管数据存在，但它返回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功能 ID，short_text_field：字符串，* GEOM：点：SRID = 4326 INFO功能导出在2077ms完成标准输出

    3. 来自（1）的示例数据：

    ID，GEOM：点：SRID = 4326，short_text_field：字符串，long_text_field_1：字符串，long_text_field_2：字符串 e9c756ef-06d6-42dd-84a9-c774ec9086ec，POINT（-117.830256 -76.799443），597Fish，“牛车？牛鱼鼠猫车鱼马鼠鱼”，“诶迪伊迎益伊迎诶迎诶伊”）< / p>

    问题：有人知道调试此方法的最佳方法吗？

    使用-a：

答案 0 :(得分：1)

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。

进行摄取时，请务必指定namespace.catalogname

同样，查询时也必须这样做。
