Questions about load data in Kylin
Hi Kylin,
I am a master student who is currently working on a project about to load
data in Apache Kylin. And I would like to know about it. Do you know how or
do you have any ideas on how to load a million rows of data ( CSV file)
into the Kylin environment? My Kylin is installed on AWS EMR.
My Kylin version is 3.0.2.
I would be appreciated if you can help. I look forward to hearing from you.
Thank you
Sincerely,
Carrie

Also, I created the hive table, but when I tried to create the cube, it
stuck on the step 1 for so long and the log said no data available . Can
you please advise ?

Hi Xiaoxiang,
I created the hive table and also created the HBase table. I transferred
the data from Hive to Hbase. After I did that, I stopped to run the Kylin
and restarted it. However, the Kylin was able to run by showing the message
" A new Kylin instance is started by hadoop. .....*"* . But I can't connect
to the UI from the browser. I was able to get into the Kylin UI before I
transferred to the HBase based on the URL <http:localhost:8157/kylin>. Can
you please advise? Maybe I did something wrong?
Thank you so much. and I appreciate your help!
Sincerely,
Carrie
