-------------------------------------------------------------
I setup a CHD 5.4 sandbox, and reproduced the problem; I noticed that the
calcite version in /usr/lib/hive/lib is v1.0; while Kylin shipped v0.9 calcite,
this will cause conflict; The problem was Kylin adds all hive/lib/* to
classpath when starts up, this is not good; (In HDP 2.2, it ships v0.9 which is
the same as Kylin, so didn't cause issue)
I updated the find-hive-dependency.sh to exclude the calcite in hive/lib
folder, I tested it works now in my CDH, the cube build and query all works;
Please download the new find-hive-dependency.sh (from the "attachement" section
of this page), replace the file in $KYLIN_HOME/bin/ folder, and then restart
Kylin server to take effective; Will commit the change to github a little bit
later;
