### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened Documentation states: Use -i or --variable to specify the variables in the configuration file, you can configure multiple But when I use -i , like ./start-seatunnel-flink-connector-v2.sh -i ckhouse="10.185.71.36" the program throws an error I try three methods ， all are useless： host = ""${ckhouse}":8123" host = "${ckhouse}:8123" host = "'${ckhouse}':8123" ### SeaTunnel Version 2.3.0 release ### SeaTunnel Config ```conf env { execution.parallelism = 1 job.mode = "BATCH" } source { Clickhouse { host = ""${ckhouse}":8123" database = "fin_dw_local" ``` ### Running Command ```shell ./start-seatunnel-flink-connector-v2.sh -i ckhouse="10.185.71.36" -c ../config/task/flink.common.bianliang.conf ``` ### Error Exception ```log Execute SeaTunnel Flink Job: ${FLINK_HOME}/bin/flink run -c org.apache.seatunnel.core.starter.flink.SeatunnelFlink /home/q/dis/apache-seatunnel-incubating-2.3.0/starter/seatunnel-flink-starter.jar --config ../config/task/flink.common.bianliang.conf -Dpipeline.name=SeaTunnel -Dckhouse=10.185.71.36 -Duserindex=0 -Ddatahour=2023-03-30 Setting HADOOP_CONF_DIR=/etc/hadoop/conf because no HADOOP_CONF_DIR or HADOOP_CLASSPATH was set.
