Hi all!
I working on updating hadoop libraries in Apache Drill project.
hadoop-hdfs uses commons-logging library, but Drill uses jcl-over-slf4j
and bans commons-logging.
I faced the following issue:
java.lang.NoClassDefFoundError:
org/apache/commons/logging/impl/Log4JLogger [1]
I even didn't find this class with the same path in any slf4j library.
Is that possible to solve the issue without enabling commons-logging in
Drill project? Looks like Log4JLogger class
in org.apache.commons.logging.impl of jcl-over-slf4j [2] could resolve
it. Should it be there? But then it will be the question to the dev list.
