Jeff Lord created ZOOKEEPER-1689:
------------------------------------
Summary: Remove JVMFLAGS completely from clients, if
CLIENT_JVMFLAGS are also set
Key: ZOOKEEPER-1689
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1689
Project: ZooKeeper
Issue Type: Bug
Components: scripts
Affects Versions: 3.4.5
Reporter: Jeff Lord
Priority: Minor
In zkCli.sh, the CLIENT_JVMFLAGS are being passed along with regular JVMFLAGS,
so the latter ends up overriding it anyhow if set. Can we please remove
JVMFLAGS completely from clients, if CLIENT_JVMFLAGS are also set (i.e. use
just one).
One example of how this can be detrimental is if you attempt to start a
zookeeper-client session on the same host that is already running zookeeper and
use the default config directory. If the zookeeper server has jmx enabled than
the client will also pick up that port and attempt to bind resulting in a
failure
# /usr/bin/zookeeper-client
Error: Exception thrown by the agent : java.rmi.server.ExportException: Port
already in use: 9010; nested exception is:
java.net.BindException: Address already in use
