安装Apache Kylin时遇到的问题

Posted 2022-11-22 wtq1993

一：当在ubuntu下执行check_env.sh时遇到问题：
KYLIN_HOME is set to /usr/local/apache-kylin-1.5.4.1-bin cat: invalid option -- '1' Try 'cat --help' for more information. -mkdir: Not enough arguments: expected 1 but got 0 Usage: hadoop fs [generic options] -mkdir [-p] ... failed to create , Please make sure the user has right to access
可能是由于get-properties.sh里的某条命令与ubuntu不相符，将get-propertie中的内容替换如下得以解决

if [ $# != 1 ]
then
    echo 'invalid input'
    exit -1
fi

result=`cat $KYLIN_HOME/conf/kylin.properties | grep -w "^$1" | grep -v '^#' | awk -F= ' n = index($0,"="); print substr($0,n+1)' | cut -c 1- |tail -1`
echo $result

二：当执行 ./check_env.sh 时遇到 mkdir: Permission denied: user=root, access=WRITE, inode="/":hdfs:supergroup:drwxr-xr-x
failed to create /kylin, Please make sure the user has right to access /kylin
   可以在check-env.sh中 将hadoop fs -mkdir -p $WORKING_DIR 变成 sudo -u hdfs hadoop fs -mkdir -p $WORKING_DIR,得以解决
