Dear
Dear Sirs/Madames
Could anyone here help me to figureout the way to use scala to query an
select SQL against kylin cube via API then turn that table result into a
dataframe in scala for other purpose?
Thank you so much for your time!

Hi Xiaoxiang,
Sir & Madames,
I use the following code to query the cube via API but I cannot use the
result as a dataframe, could you suggest a way to do that because it is
very important for our project.
Thanks and best regards

Hi:
In my opinion, what you are describing is a normal phenomenon.
When executing the cube build job, kylin will add the task of each step in the
job into a map. The FetcherRunner will periodically fetch the tasks that can be
executed from the map and add them to the JobPool. If it is found
I have obeserved that when the "kylin.job.max-concurrent-jobs" properties is
used for a cluster configuration and set to for e.g. lets say value 1. Then
for a given cube building job cluster, during a cube build if another cube
build request is submitted the currently running job is set

There are three ways of cube migration in the document of cube migration. Which
one do you use? And what's your kylin version? Is the Hadoop version used by QA
