My model have 7 tables,a cube have 15 dimensions, in the “Convert Cuboid Data to HFile” step to start too many maps and reduces(maps 500+,reduces 1. 4k+),This step expend all resources of the small cluster.
I set these parameters in the cluster: dfs.block.size=256M hive.exec.reducers.bytes.per.reducer=1073741824 hive.merge.mapfiles=true hive.merge.mapredfiles=true hive.merge.size.per.task=256M kylin_hive_conf.xml this file uses the default settings Where can I turning performance optimization? Thanks.
