> Custom Log4j properties for each flink job
> ------------------------------------------
>
> Key: FLINK-11324
> URL: https://issues.apache.org/jira/browse/FLINK-11324
> Project: Flink
> Issue Type: Improvement
> Components: Legacy Components / Flink on Tez
> Affects Versions: 1.6.2
> Reporter: Ankit Sharma
> Priority: Minor
> Labels: stale-minor
>
> It would be a good idea if we can have a custom log4j files/location for each
> job we run via flink.
> Currently there is no option for that in flink command.
> I tried providing log4j properties by using below command but it didn't
> worked for me:
> flink run /usr/lib/flink/examples/batch/WordCount.jar
> -Dlog4j.configuration=~/log4j_ABC.properties
> So, i checked the source code of flink and found that the path of log4j
> proerpties are hard-coded in flink command script, so did few twik to make it
> work. It worked for me but i am really not sure about what other components
> it might affect.
> Below are the steps/changes done:
> 1. Add below code in $FLINK_HOME/bin/flink file just after the config.sh
> being called, this code will add a new environment variable FLINK_LOG_SETTING
> in which we will be setting the log4j-cli.properties absolute path:
> if [ -z "$FLINK_LOG_SETTING" ]; then FLINK_LOG_SETTING=$FLINK_CONF_DIR;
> fi
> 2. In log_setting variable mentioned in flink, change the
> -Dlog4j.configuration as below:
> log_setting=(-Dlog.file="$log"
> -Dlog4j.configuration=file:"$FLINK_LOG_SETTING"/log4j-cli.properties
> -Dlogback.configurationFile=file:"$FLINK_CONF_DIR"/logback.xml)
> 3. save the changes.
> 4. Now before executing any flink job in cli, export the FLINK_LOG_SETTING to
> any custom path where you have log4j-cli.properties present for the
> respective job.
> $ export FLINK_LOG_SETTING=/home/hadoop/test
