Question

我正在尝试在Ubuntu 16.04中安装Apache Kylin。

我已安装：

在伪分布式模式下运行hadoop 3.1.2（fs.default.name：hdfs：// localhost：9000）
apache配置单元3.1.2和db derby 10.14.2.0（配置配置单元使用db derby）
在伪分布式模式下的hbase 1.4.10（使用hdfs：// localhost：9000 / hbase）

但是当我打电话时：

hbase外壳
hbase（main）：001：0>列表

获取错误：

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:.*'

当我打电话时：

ssh localhost
kylin.sh开始

获取错误

Answer 1

从错误中可以明显看出您的HBase没有运行；请确保HBase良好。

Answer 2

Hadoop历史悠久且复杂，因此我们建议您使用经过良好测试的Hadoop发行版，例如CDH和HDP，但不要使用自定义Hadoop环境。如果您要进行PoC并想快速学习Kylin，请使用Docker映像https://hub.docker.com/r/apachekylin/apache-kylin-standalone。如果要在更正式的Hadoop环境中使用Kylin，可以使用CDH 5.x或HDP 2.x Hadoop发行版吗？如果您还有其他问题，请通过用户邮件列表与Kylin社区联系。
