> Hi all,
> im using Kylin to speed up query HDFS.
> Which 2.5 billions records per day. When i'm using Kylin and load hive table, it make a mapreduce on my server, 2969 map and 1 reduce with only 1 table. My datasource about 10 tables. And it so slow. I attached an image.
> So, can i speed up process "Load hive table" to create model and cubes so quickly?
> Exam use spark (because mapreduce so slow)?
> Best regards, Thanks all
