我在试密码-

from org.apache.pig.scripting import *
P= Pig.compile("""
load_job_data= LOAD 'ics_job_detail_analytics_2016' using org.apache.hive.hcatalog.pig.HCatLoader();
job_detail_out= LIMIT load_job_data 2;
store job_detail_out into '$job_detail' using PigStorage(',');
""")

for i in range(1): 
    params= {}
    job_detail= "job_detail_out"
    params["job_detail"]= job_detail 
    Pig.fs("rmr " +job_detail) 
    bound= P.bind(params)
    stats= bound.runSingle()
    print(type(stats))
    if not stats.isSuccessful():
        raise 'failed'
    print(type(stats.result("job_detail_out")))
    #itr= stats.result("job_detail_out").iterator()
    #while itr.hasNext():
    #    print(itr.next())

它总是给我'nonetype'，因此我不能遍历输出。有什么帮助吗？下面是输出的最后几行-
