Seems there your Java running time environment was not clean. Please check the JAVA_HOME and PATH system variable, use the echo command see what output from them.
By the way the Kylin also can run in Hadoop clusters which use JDK1.7, just a simple modify. The steps like this: 1. modify the HBase conf file which name is hbase-env.sh, add export JAVA_HOME=/path/of/jdk1.8 2. append the below configure into kylin_job_conf.xml and kylin_job_conf_inmem.xml files. <property> <name>mapred.child.env</name> <value>JAVA_HOME=/usr/lib/java/jdk1.8.0_201</value> </property> <property> <name>yarn.app.mapreduce.am.env</name> <value>JAVA_HOME=/usr/lib/java/jdk1.8.0_201</value> </property> Hope those can help you! -- Sent from: http://apache-kylin.74782.x6.nabble.com/
