我正在azure上使用hortonworks沙盒，我正在学习hadoop入门教程“Lab3-pig风险因素分析”
http://hortonworks.com/hadoop-tutorial/hello-world-an-introduction-to-hadoop-hcatalog-hive-and-pig/#section_5
在完成所有步骤并运行此pig脚本之后：

a = LOAD 'geolocation' using org.apache.hive.hcatalog.pig.HCatLoader();
b = filter a by event != 'normal';
c = foreach b generate driverid, event, (int) '1' as occurance;
d = group c by driverid;
e = foreach d generate group as driverid, SUM(c.occurance) as t_occ;
g = LOAD 'drivermileage' using org.apache.hive.hcatalog.pig.HCatLoader();
h = join e by driverid, g by driverid;
final_data = foreach h generate $0 as driverid, $1 as events, $3 as totmiles, (float) $3/$1 as riskfactor;
store final_data into 'riskfactor' using org.apache.hive.hcatalog.pig.HCatStorer();

单击“执行”将启动作业，但它几乎立即失败，并出现以下错误：

hdfs中根本没有/tmp/.pigjobs/的文件。因此，就好像pig脚本需要在那里创建一个文件才能执行，但却找不到它。我使用“-usehcatalog”参数和“executing on tez”
不确定这是一个权限错误，还是一个azure错误，但这是非常令人沮丧的刚刚开始的教程，没有“沙盒”设置，以通过前几节课，而不必作出无数的调整配置设置。非常感谢您的帮助！
