Hi，liam I just met your same problem a few days ago and fixed it. The difference is hive-0.13.1 in our enviroment, but I think the reason is same. The reason is that org.apache.hadoop.mapreduce.JobContext is class in hadoop-1 but changed to interface in hadoop-2, and your hive-hcatalog-core.jar must be complied on hadoop-1. As I know, hive-hcatalog-core-0.13.1.jar in maven.apache.org is complied on hadoop-1, but not clear about hive 1.0.1. I think you should have a try, to re-complie your hive-hcatalog-core jar on hadoop-2.
Good luck and looking forward your good news -:) Best Regards, Yerui Sun [email protected] > 在 2015年7月31日，16:40，liam <[email protected]> 写道： > > Hi, > Can anyone help this? > Thx! > > 2015-07-30 18:11 GMT+08:00 liam <[email protected]>: > >> Hi,all >> I failed in building the sample cube “kylin_sales_cube”,I found the error >> message from the logs(showed bellow). >> Did anyone get the same issue before?
