Hello everyone, I am a newbie.
I am learning the flink-sql-submit project. From @Jark Wu : https://github.com/wuchong/flink-sql-submit My local environment is: 1. flink1.9.0 standalone 2. kafka_2.11-2.2.0 single I configured Flink Connectors and Formats jars to $FLINK_HOME/lib . Reference: https://ci.apache.org/projects/flink/flink-docs-release-1.9/dev/table/connect.html#connectors Then I run flink-sql-submit , sh run.sh q1 Throw java.lang.ClassNotFoundException: com.mysql.jdbc.Driver. My question is: I configured mysql-connector-java in the pom.xml file, mvn build jar include com.mysql.jdbc.Driver. Why is this error still reported? I put the jar package in $FLINK_HOME/lib and the problem can be solved. Do you need to put these jars in $FLINK_HOME/lib when the project relies on too many jar packages? If I don't put mysql-connector-java.jar in $FLINK_HOME/lib, how can I solve this problem? Can @Jark Wu give me some advice? Or can someone give me some advice? Thank you. 1. pom.xml <dependency> > <groupId>mysql</groupId> > <artifactId>mysql-connector-java</artifactId> > <version>5.1.38</version> > </dependency> 2. mvn clean; mvn package $ ll -rth target > > [±master ●] > total 32312 > drwxr-xr-x 3 alex staff 96B Oct 30 11:32 generated-sources > drwxr-xr-x 5 alex staff 160B Oct 30 11:32 classes > drwxr-xr-x 3 alex staff 96B Oct 30 11:32 maven-archiver > -rw-r--r-- 1 alex staff 7.2M Oct 30 11:32 > flink-sql-submit-1.0-SNAPSHOT.jar > -rw-r--r-- 1 alex staff 8.2M Oct 30 11:32 flink-sql-submit.jar > 3. flink-sql-submit.jar include java.sql.Driver " zip.vim version v28 > " Browsing zipfile > /Users/alex/IdeaProjects/alex/flink_learn/flink-sql-submit/target/flink-sql-submit.jar > " Select a file with cursor and press ENTER > > META-INF/MANIFEST.MF > META-INF/ > q1.sql > user_behavior.log > com/ > com/github/ > com/github/wuchong/ > com/github/wuchong/sqlsubmit/ > com/github/wuchong/sqlsubmit/SqlSubmit$1.class > com/github/wuchong/sqlsubmit/SqlSubmit.class > com/github/wuchong/sqlsubmit/SourceGenerator.class > com/github/wuchong/sqlsubmit/cli/ > com/github/wuchong/sqlsubmit/cli/SqlCommandParser$SqlCommandCall.class > com/github/wuchong/sqlsubmit/cli/SqlCommandParser.class > com/github/wuchong/sqlsubmit/cli/SqlCommandParser$SqlCommand.class > com/github/wuchong/sqlsubmit/cli/CliOptions.class > com/github/wuchong/sqlsubmit/cli/CliOptionsParser.class > META-INF/maven/ > META-INF/maven/com.github.wuchong/ > META-INF/maven/com.github.wuchong/flink-sql-submit/ > META-INF/maven/com.github.wuchong/flink-sql-submit/pom.xml > META-INF/maven/com.github.wuchong/flink-sql-submit/pom.properties > META-INF/services/ > META-INF/services/java.sql.Driver > com/mysql/ > com/mysql/fabric/ > com/mysql/fabric/FabricCommunicationException.class > com/mysql/fabric/FabricConnection.class > com/mysql/fabric/FabricStateResponse.class > com/mysql/fabric/HashShardMapping$ReverseShardIndexSorter.class > com/mysql/fabric/HashShardMapping.class > com/mysql/fabric/RangeShardMapping$RangeShardIndexSorter.class > com/mysql/fabric/RangeShardMapping.class > com/mysql/fabric/Response.class > com/mysql/fabric/Server.class > com/mysql/fabric/ServerGroup.class > com/mysql/fabric/ServerMode.class > com/mysql/fabric/ServerRole.class > etc ... > $FLINK_DIR/bin/flink run -d -p 3 target/flink-sql-submit.jar -w "${PROJECT_DIR}"/src/main/resources/ -f "$1".sql Eerror: 2019-10-30 10:27:35 java.lang.IllegalArgumentException: JDBC driver class not found.

You can create a fat jar (also called Uber jar) that includes all dependencies in your application jar. I would avoid to put things in the Flink lib directory as it can make maintenance difficult. Eg deployment is challenging, upgrade of flink, providing it on new nodes etc. > Am 30.10.2019 um 04:46 schrieb Alex Wang <[hidden email]>: > > > Hello everyone, I am a newbie. > I am learning the flink-sql-submit project.

Hi Franke,
From the information provided by Alex: >> mvn build jar include com.mysql.jdbc.Driver. it seems he has packaged a fat jar?

Hello Yang, Frank
Thank you for your reply. Frank I have created a fat jar called flink-sql-submit.jar , the file size is 8.2M . You can create a fat jar (also called Uber jar) that includes all > dependencies in your application jar. > > I would avoid to put things in the Flink lib directory as it can make > maintenance difficult. Eg deployment is challenging, upgrade of flink, > providing it on new nodes etc. > I am in favor of your point of view, I want to maintain the project's dependencies, rather than put it in the Flink lib directory. I will continue to solve this problem. I will give you feedback if I have an answer.
