Description
csv原始数据中有个create_time时间字段格式为2018-06-18-16.39.05.214000（yyyy-MM-dd-HH.mm.ss.SS），导入hive时想变成2018-06-18 16:39:05（yyyy-MM-dd HH:mm:ss）需要怎么配置？
目前使用txtfilereader读、hdfsWriter写：
- txtfilereader：create_time字段"type"="date"，"format"="yyyy-MM-dd-HH.mm.ss"（指定为其他格式会报错解析不了日期）
- hdfsWriter中的create_time字段"type"="date"，"format"="yyyy-MM-dd HH:mm:ss" 并没有效果
如何再将 txtfilereader的"yyyy-MM-dd-HH.mm.ss"转换为hdfsWriter的"yyyy-MM-dd HH:mm:ss"呢？
