Hi, Usually this is caused that HBase's script didn't inheritate the "HBASE_CLASSPATH" environment varaible (Kylin depends on it to attache Hive jars to classpath).
Go to the HBase installation path, and then grep "HBASE_CLASSPATH" in the `hbase` shell file, you should find something like: export HBASE_CLASSPATH=$HADOOP_CONF:$HADOOP_HOME/*:$HADOOP_HOME/lib/*:$ZOOKEEPER_HOME/*:$ZOOKEEPER_HOME/lib/*:$HBASE_CLASSPATH Above is a good sample, as it will keep the original value of $HBASE_CLASSPATH; But in some distribution like EMR 5.0, it just set the HBASE_CLASSPATH value instead of appending, then it will cause the hive jar not on Kylin's classpath. You need manually correct that. I will add this to FAQ page. 2016-10-17 17:03 GMT+08:00 张磊 <121762...@qq.com>: > I install kylin(apache-kylin-1.5.4.1-hbase1.x-bin) in EMR5.0.0， while i > operate on web, there is some error, i do not install hcatalog in emr.
