Hive：python UDF在關閉運算符時給出了「Hive運行時錯誤」

我有一個要求，可以根據某些業務邏輯將幾個日期格式轉換爲布爾條件。Hive：python UDF在關閉運算符時給出了「Hive運行時錯誤」

但是我從Hive調用python腳本時失敗了。下面是我寫的日期格式轉換爲樣品1列中的腳本：

import sys 

def getYearMonthFromStringDate(dt): 
    year=0 
    month=0 
    try: 
     ss=dt.split('-') 
     year=ss[0] 
     month=ss[1] 
    except ValueError: 
     print "Error parsing date string %s" %dt 
    return int(year)*100+int(month) 

for line in sys.stdin: 
    tempArr=line.split('\t') 
    accountgl0s=tempArr[0] 
    agl0 = getYearMonthFromStringDate(accountgl0s) 
    output_list = [accountgl0s, ag10] 
    print '\t'.join(output_list)

我使用下面的命令添加在分佈式緩存中的文件：

add file /folder/date.py

現在，我打電話這條巨蟒使用變換如下我蜂巢表的山坳accountgl0s功能：

Input column accountgl0s = '2016-10-01' 

select transform(accountgl0) using 'python date.py' as (accountgl0s,agl0) from sample;

我的期望輸出應該是2016-10-01 201610。但我得到下面的錯誤：

上述這些錯誤消息，有像開始工作= job_1480642810315_083110，跟蹤URL = HTTP輸出中的URL：// hadoop-test15.int.xxxxxx.com:8088/proxy/application_148012122315_081130/，請訪問此網址，您可以找到有關python錯誤消息的信息。 –

你爲什麼要編寫一個自定義的python腳本來分割一個字符串？ – gobrewers14

其實我需要在python腳本中包含更多的biz邏輯。但爲了測試目的，我只是通過轉換日期字符串來測試一小段代碼。

您是否在該腳本中看到任何問題？

你必須改變你的類型變量時，你想計算數量浮動：

f_accountgl0s = float(accountgl0s)
