Karl Wright created ZOOKEEPER-2889:
--------------------------------------
Summary: Zookeeper standalone instance startup references logging
classes incompatible with log4j-1.2-api
Key: ZOOKEEPER-2889
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2889
Project: ZooKeeper
Issue Type: Bug
Affects Versions: 3.4.8
Reporter: Karl Wright
Starting Zookeeper in the following way causes "ClassNotFoundException" errors,
and aborts, in a log4j 2.x environment:
{code}
"%JAVA_HOME%\bin\java" %JAVAOPTIONS%
org.apache.zookeeper.server.quorum.QuorumPeerMain zookeeper.cfg
{code}
The log4j 2.x jars in the classpath are:
{code}
log4j-1.2-api
log4j-core
log4j-api
{code}
It appears that the Zookeeper QuorumPeerMain class is incompatible with the
limited log4j 1.2 API that log4j 2.x includes. Zookeeper 3.4.8 works fine with
log4j 2.x except when you start it as a service in this way.
