Hi Kylin dev, The first step is building cube is to CreateFlatHiveTable, it will call a few hive configuration commands, such as CreateFlatHiveTableStep line 78 and 79. set mapreduce.job.reduces=numReduces set hive.merge.mapredfiles=false
Are these commands necessary for the cube building? Could we configure them in files? I met some cases, where the hiveserver would say "Configuration is not allowed to modify at runtime". It will break the build. Maybe there are some other hard code hadoop commands still. It will be more friendly if they could turn off on demand. -- With Warm regards Yiming Liu (刘一鸣)
