Guocheng Zhang commented on INLONG-744: --------------------------------------- Hi, [~xinzhuxianshenger] , First of all thank you for your attention The modification of this PR is for the change of the CLI command, you can also see that other classes in this CLI directory follow this definition, so this place is not an bug. In the CLI command we defined a principle: we only record the information after the program is successfully started to the log file; if the program fails to start abnormally due to the wrong startup parameter, we output through System.err.println(). So, I will revert this PR, thanks > Error log, should use log4j > --------------------------- > > Key: INLONG-744 > URL: https://issues.apache.org/jira/browse/INLONG-744 > Project: Apache InLong > Issue Type: Improvement > Components: inlong-tubemq > Reporter: Young Chou > Assignee: Young Chou > Priority: Minor > Labels: pull-request-available > Time Spent: 20m > Remaining Estimate: 0h > -- This message was sent by Atlassian Jira (v8.3.4#803005)
