Hi,
my cube contains sigle table,it's size about 70M,
but it contains 2 TopN measures.
when buiding cube,it alway wait in
#8 Step Name: Build N-Dimension Cuboid Data : 1-Dimension
wait in this step's map sort stage for 1 hour until map task timeout,then container kill it.
excuse me, how to deal with this problem..

How many mappers running? What's the configuration of the hadoop node? and
what's your kylin version?

Try give more memory to your mapper tasks. You can modify
conf/kylin_job_conf.xml to adjust MR configurations.
