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! ------------------ ???????? ------------------ ??????: "Lijun Cao"<641507...@qq.com>; ????????: 2018??12??13??(??????) ????10:27 ??????: "user"<user@kylin.apache.org>; ????: Re: Didn't find KYLIN_CONF or KYLIN_HOME, please set one of them Hi, ??????: Have you try to export KYLIN_HOME as environment variable?
