Hi ebrahim zare:
Derby or MySQL is needed but they are not for Kylin directly. Actually they are
used to store the metadata of Hadoop??s components(For example, Hive). For
Kylin, both metadata and cube data are stored in HBase. So you should configure
HBase and HDFS correctly.
Besides, you
Exactly; Thank you jiatao for the comments!

Hello,
At the moment I'm working in Business Intelligence (BI) department and we are
working with IBM Cognos products (reporting, cubes (MOLAP, ROLAP, dynamic
cubes). We also have a big data department that is based on Cloudera.
I am interested in Apache Kylin product and I'd like to know if
I installed Java and Hadoop and Hbase and Hive and Spark and Kylin.
hadoop-3.0.3
hbase-1.2.6
apache-hive-2.3.3-bin
spark-2.2.2-bin-without-hadoop
apache-kylin-2.3.1-bin
I will be grateful if someone in Help me with Kyle's installation and
configuration them.

persistency; You only need to make sure Hive/HBase/Hadoop working fine.
I see you're using Hadoop 3; please note that, only from 2.5, Kylin
provides the binary package for Hadoop 3. Besides, we only tested it on
HDP 3 and
You are welcome, ShaoFeng! Storage and query engine are inseparable and
should design together for fully gaining each other's abilities. And I'm
very excited about the new coming columnar storage and query engine!

Hi Goran,
I do know some users are using Kylin to replace Cognos Cubes, getting big
improvements in terms of performance, capability, flexibility, and others.
Usually, that is a total solution with a set of tools and professional
services from vendors. If you're interested, I can find someone to
Hi,
How can I assign the namespace of hbase. I don’t want to use the default

Hi Scott Fan:
You can find the namespace configuration in $KYLIN_HOME/conf/kylin.properties.
Just as the picture shown below:
