获取表数据，向表写数据，行记录Record报错

解决：

找不到分区，也就是mytable表没有test分区

可以先添加分区

mytable.create_partition('pt=test')

有test分区后就能写如数据了

>>> with mytable.open_writer(partition='pt=test') as writer:
...     records = [[111],                
...                 [222],
...               [333],
...               [444]]
...     writer.write(records)

报错信息：

>>> with mytable.open_writer(partition='pt=test') as writer:
...     records=[1,2,3,4]                                   
...     writer.writer(records)                              
...

AttributeError: 'RecordWriter' object has no attribute 'writer'
>>>   

解决：
writer.write(records)中第二个writer多个r，如下
>>> 
>>> with mytable.open_writer(partition='pt=test') as writer:
...     records = [[111],                
...                 [222],
...               [333],
...               [444]]
...     writer.write(records)
...
