python - Hive Python UDF

Question

我正在使用此Python UDF脚本:

import sys
import collections 
import datetime
import re

try:
    for line in sys.stdin: 
        line=line.strip()
        number,sd=line.split('\t')
        sd=sd.lower()
        sd=sd.split(' ')
        new_sd_list=collections.OrderedDict(collections.Counter(sd))
        new_sd=' '.join(new_sd_list)
        print('\t'.join([str(number),str(new_sd])))
except:
    print(sys.exc_info())

在Putty中执行以下命令。

SELECT TRANSFORM(number,shortdescription) USING 'python name.py' \
   AS (number,shortdescription) FROM table;

我收到此错误:

Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: Hive Runtime Error while processing row {"number": "ABC00548","shortdescription":""Master data inconsistency check in India Optimizer."}
