Hello,
I am using latest (2.6) version of Kylin and I am following instructions
from https://kylin.apache.org/docs/tutorial/cube_streaming.html to build
a demo streaming cube.
At a BUILD CUBE job, I can see in monitor tab in "Hive Cleanup" step an
error occurs by the following java exception:
java.lang.RuntimeException: Failed to read kylin_hive_conf.xml
at
org.apache.kylin.common.util.SourceConfigurationUtil.loadXmlConfiguration(SourceConfigurationUtil.java:87)

at java.lang.Thread.run(Thread.java:748)
Then if I try to run a SQL query in Insight tab the following exception
is thrown:
java.lang.RuntimeException: fail to locate kylin.properties
while executing SQL: "select minute_start, count(*), sum(amount),
sum(qty) from streaming_sales_table group by minute_start order by
minute_start LIMIT 50000"
and generally, it seems that it can't find any Kylin configuration files
afterwards.
I have set properly JAVA_HOME, HADOOP_HOME, HIVE_HOME, HBASE_HOME,
KYLIN_HOME environment variables.
What could be the reason for that?
