Summary: No logs print in kylin.log file and met error "Error:
Could not find or load main class

Key: KYLIN-4070
URL: https://issues.apache.org/jira/browse/KYLIN-4070
Project: Kylin
Issue Type: Bug
Environment: apache-kylin-2.6.2-bin-hbase1x hadoop-2.7.7
hbase-1.2.11 hive-2.3.4
Reporter: xiangakun
Hello friends,
I am using kylin with version 2.6.2, and the relied components are lists below,
I start the kylin server successfully and met the error
"org.apache.kylin.rest.exception.InternalErrorException:
org/apache/hadoop/hive/conf/HiveConf" when loading hive meta data. I updated
the configuration from "export
HBASE_CLASSPATH_PREFIX=${KYLIN_HOME}/conf:${KYLIN_HOME}/lib/*:${KYLIN_HOME}/ext/*:${HBASE_CLASSPATH_PREFIX}"
to "export
HBASE_CLASSPATH_PREFIX=${KYLIN_HOME}/conf:${KYLIN_HOME}/lib/*:${KYLIN_HOME}/ext/*:{color:#FF0000}${hive_dependency}{color}:${HBASE_CLASSPATH_PREFIX}"
in kylin.sh file. it did work fine. However, after this action, I found no
more messages could be produced in logs/kylin.log file. I removed kylin.log
file, and after restarted the kylin server, kylin.log file was not created any
more. It's seems too stange.
What's more, when I create a cube and build it, the error happens in step 3, it
shows "
Error: Could not find or load main class
org.apache.hadoop.mapreduce.v2.app.MRAppMaster".
In fact, I used the same configuration in yarn-site.xml and mapred-site.xml
files with kylin version 2.1.0 for a long time, it worked fine and never met
such error.
Does anyone meet the same problem before? Hope receive your kindly help soon.
Thanks in advance.
Best Regards
xiangakun
