Hi,
We are evaluating Apache Kylin. I need some help setting up Kylin and
understand its working.
I have Clouder VM 5.13 and I started most of the services using cloudera
manager and executed
sample scripts
Command history
export KYLIN_HOME=/usr/local/kylin/apache-kylin-2.3.0-bin
124 export PATH=$KYLIN_HOME/bin:$PATH
125 echo $PATH
128 sudo su -p hdf bin/check-env.sh
129 sudo su -p hdfs bin/check-env.sh
130 sudo su -p hdfs bin/sample.sh
Got a permission error gave "hdfs" permission on all the folders in kylin
131 sudo su -p hdfs mkdir
/usr/local/kylin/apache-kylin-2.3.0-bin/sample_cube/metadata
132 sudo su -p hdfs
135 chown -R . hdfs
136 chown hdfs -R /usr/local/kylin/
137 sudo chown hdfs -R /usr/local/kylin/
138 ls -all
Executed sample script
139 sudo su -p hdfs bin/sample.sh
