[jira] [Updated] (LOG4J2-3403) java.lang.ClassNotFoundException: org.slf4j.bridge.SLF4JBridgeHandler
[ https://issues.apache.org/jira/browse/LOG4J2-3403?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jitin Dominic updated LOG4J2-3403:
----------------------------------
Description:
I'm using the latest (v2.17.1) log4j2 dependencies in my grails 2.5.4 application. Following are the dependencies used:
* log4j-api
* log4j-core
* log4j-1.2-api
* log4j-slf4j-impl
We also have spark dependencies in our application for generating parquet files:
{code:java}
compile ("org.apache.spark:spark-core_2.12:3.1.2") {
exclude group: 'org.slf4j'
}
compile ("org.apache.spark:spark-sql_2.12:3.1.2") {
exclude group: 'org.slf4j'
}
compile ("org.apache.spark:spark-catalyst_2.12:3.1.2") {
exclude group: 'org.slf4j'
} {code}
When we try to generate parquet file, we get following exception:
{code:java}

This is happening because we have excluded _org.slf4j_ from the spark dependencies as mentioned above.
When we try to include {_}org.slf4j{_}, we keep getting warning regarding multiple bindings of {_}slf4j{_}.
Can someone confirm if there's some issue with the configuration or is it a bug?
