回复： Didn't find KYLIN_CONF or KYLIN_HOME, please set one of them

[知猪侠 <38...@qq.com>]

Hi, Lijun Cao:
On kylin node, I have exported KYLIN_HOME as environment variable, and all cubes have been running for more than one month, this problem was suddenly happened.


I found a url : https://issues.apache.org/jira/browse/KYLIN-1229?jql=text%20~%20%22Didn%27t%20find%20KYLIN_CONF%20or%20KYLIN_HOME%2C%20please%20set%20one%20of%20them%22
It says about "Didn't find KYLIN_CONF or KYLIN_HOME, please set one of them", it was reported by Shaofeng SHI, but I'm not sure if it is similar to my problem.


Thank you!

Hi, 知猪侠:

Have you try to export KYLIN_HOME as environment variable?
