["Feng, Zhutian" <zh...@intel.com>]

Maybe something different between OpenJDK and Oracle JDK ?

I'm using Java 8 (on azure hdinsight and aws emr), it runs well.

java -version
openjdk version "1.8.0_151"
OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12)
OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

I think this problem is a jdk bug

The log above shows that the default configuration was loaded, not from conf/kylin.pproperties ,and kylin.log and kylin.out no other errors，i tried set KYLIN_CONF in /etc/profile and setenv.sh,but it does not work,
my env is :
cdh 5.8.4
kylin 2.1.0-cdh57

How can I solve this problem?
