Issues when trying to modify log4j.properties

[digui]

Hi y'all.

I'm trying to export metrics and logs to AWS cloudwatch, but while following their tutorial to do so, I ended up facing this error when trying to initialize my cluster with an init script they provided.

This is the part where the script fail

# configure cloudwatch agent for driver & executor
if  [  ! -z $DB_IS_DRIVER ] && [ $DB_IS_DRIVER = TRUE ] ; then
  sed -i '/^log4j.appender.publicFile.layout/ s/^/#/g' /home/ubuntu/databricks/spark/dbconf/log4j/driver/log4j.properties
  sed -i '/log4j.appender.publicFile=com.databricks.logging.RedactionRollingFileAppender/a log4j.appender.publicFile.layout=com.databricks.labs.log.appenders.JsonLayout' /home/ubuntu/databricks/spark/dbconf/log4j/driver/log4j.properties
else
   sed -i '/^log4j.appender.console.layout/ s/^/#/g' /home/ubuntu/databricks/spark/dbconf/log4j/executor/log4j.properties
   sed -i '/log4j.appender.console.layout=org.apache.log4j.PatternLayout/a log4j.appender.console.layout=com.databricks.labs.log.appenders.JsonLayout' /home/ubuntu/databricks/spark/dbconf/log4j/executor/log4j.properties
fi

This is the error:

sed: can't read /home/ubuntu/databricks/spark/dbconf/log4j/executor/log4j.properties: No such file or directory

I'm not familiar with java at all, so It's being kinda hard to understand what I should do here. Should I install log4j manually or something?

Thanks in advance!

Did you figure out what to do? We're facing the same issue, the script works for the executors.
I was thinking on adding an if that checks if there is log4j.properties and modify it only if it exists
