Install Apache Kylin in custom environment

Question

I'm trying to install Apache Kylin in Ubuntu 16.04.

I installed:

• hadoop 3.1.2 in pseudo distributed mode (fs.default.name: hdfs://localhost:9000)
• apache hive 3.1.2 and db derby 10.14.2.0 (config hive use db derby)
• hbase 1.4.10 in pseudo distributed mode (using hdfs://localhost:9000/hbase)

but when i call:

• hbase shell
• hbase(main):001:0> list

get error:

ERROR: Can't get master address from ZooKeeper; znode data == null

Here is some help for this command:
List all user tables in hbase. Optional regular expression parameter could
be used to filter the output. Examples:

  hbase> list
  hbase> list 'abc.*'
  hbase> list 'ns:abc.*'
  hbase> list 'ns:.*'

and when i call:

• ssh localhost
• kylin.sh start

get error

Answer 1

From the error, obviously your HBase is not running; Please make sure HBase is good.

Answer 2

Hadoop has a long history and it is complex, so we recommend you to use some well-tested Hadoop Distribution such as CDH and HDP, but not a custom Hadoop environment. If you are do a PoC and want to learn Kylin quickly, please use Docker image https://hub.docker.com/r/apachekylin/apache-kylin-standalone. If want to use Kylin in a more formal Hadoop environment, could you please use a CDH 5.x or HDP 2.x Hadoop Distribution? If you have more question, please contact Kylin community by user mailing list.
