Konstantin Knauf reopened FLINK-11324: -------------------------------------- Re-opening in accordance with https://issues.apache.org/jira/browse/FLINK-23206. > 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: auto-closed > > 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 > -- This message was sent by Atlassian Jira (v8.3.4#803005)
