記錄一個坑，python連Impala，插入數據到Kudu，會有特殊字符問題，冒號，涉及到時間格式與ip地址等場景
>>> >>>from impala.dbapi import connect
>>> >>>host='xx.xx.xx.xx'
>>> >>>conn = connect(host=host, port=25001, timeout=3600)
>>> >>>cursor = conn.cursor()
>>> >>>sql = "Insert INTO temp_table (access_time,news_id,guid,account_id) values(%s,%s,%s,%s)"
>>> >>>para = ('2018-09-13 18:47:47',558952,'fsd','fsdfsd')
>>> >>>cursor = conn.cursor()
ERROR:

大家可以看到impala解析的時候，將時間格式解析成： '2018-09-13 18'fsdfsd'7'fsdfsd'7'
>>> >>> sql = "Upsert INTO temp_table (access_time,news_id,guid,account_id) values('{0}',{1},'{2}','{3}')".format('2018-09-13 18:47:47','558952','fsd','fsdfsd')
sql="Upsert INTO temp_table (access_time,news_id,guid,account_id) values('2018-09-13 18:47:47',558952,fsd,fsdfsd)"
>>> >>> cursor.execute(sql)
>>> >>> ok
