What happened

I downloaded apache-streampark_2.12-2.1.4-incubating-bin.tar.gz in CentOS7.9,and untar it. I configured environment variables according to document as follows:

export JAVA_HOME=/opt/jdk
export HADOOP_HOME=/opt/hadoop
export HADOOP_CONF_DIR=/opt/hadoop/etc/hadoop
export HADOOP_HDFS_HOME=/opt/hadoop
export HADOOP_YARN_HOME=/opt/hadoop
export HADOOP_MAPRED_HOME=/opt/hadoop
export PATH=${HADOOP_HOME}/bin:${JAVA_HOME}/bin:${PATH}
export CLASSPATH=.:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar

I added mysql-connector-j-8.0.33.jar and flink-shaded-hadoop-3-uber-3.1.1.7.2.9.0-173-9.0.jar to lib directory in streampark. I executed "bash /opt/streampark/bin/startup.sh" and found the service didn't work properly. The log indicated some errors. I also try the streampark docker image 2.1.4. I started the containor and entered it and executed "bash streampark.sh start_docker" and found same errors.

Disable websocket in StreamPark. the front-end polling to request data from the back-end. Only info notification is used here.

hi @wolfboys, i would like to try this.

I found probable cause. I moved flink-shaded-hadoop-3-uber-3.1.1.7.2.9.0-173-9.0.jar to directory /streampark/lib, and when I execute startup.sh, the error happened. I moved flink-shaded-hadoop-3-uber-3.1.1.7.2.9.0-173-9.0.jar out from directory /streampark/lib, and when I execute startup.sh, the service streampark works.
