Kylin lost connection to zookeeper and keep on reconnect and fail
in "Build Dimension Dictionary" step
Hi,
I'm a beginner of Kylin. I encountered a problem when building a cube which
blocked me in "Build Dimension Dictionary" step. Here is the log:

Kylin also stoped after several times. When I restart kylin, it still trying
and failing.
I've checked zookeeper, seems no problem during this period. Does anyone
know what happened and how can I fix the problem?
This is my environment:
Hadoop 2.7.2
Spark 1.6.2
Hbase 1.2.2
Zookeeper 3.4.6
Hive 2.1.0
Kylin 1.5.3
Thanks,
Minghao Feng

There is not much context of the original problem. But from the title, if
Kylin lost connection to zookeeper, it is likely a environment stability
problem.
