    我有如下的测试数据:

     test_a      test_b   test_c   test_d   test_date
        -------------------------------------------------
    1   a           500      0.1      111      20191101
    2   a           NaN      0.2      NaN      20191102
    3   a           200      0.1      111      20191103
    4   a           400      NaN      222      20191104
    5   a           NaN      0.2      333      20191105
    

    我现在导入的数据中有空字符串,在 pandas 中,对空值做了处理 df = df.fillna('')

    COLUMN                           CELL                                             
     test:test_a                      timestamp=1578389750838, value=a                  
     test:test_b                      timestamp=1578389788675, value=                   
     test:test_c                      timestamp=1578389775471, value=0.2                
     test:test_d                      timestamp=1578449081388, value=
    

    如何让它在 Hbase 查询 get 'test', 'a201911012'后是如下结果:

    COLUMN                           CELL                                              
     test:test_a                      timestamp=1578389750838, value=a                  
     test:test_c                      timestamp=1578389775471, value=0.2  
    

    感谢大神给到的任何建议!!
