zkServer.sh script needs to track whether ZK is already running or not
----------------------------------------------------------------------
Key: ZOOKEEPER-1071
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1071
Project: ZooKeeper
Issue Type: Bug
Components: scripts
Reporter: Roman Shaposhnik
If one repeatedly invokes:
{noformat}
/usr/lib/zookeeper/bin/zkServer.sh start
{noformat}
after the initial start 2 bad things happen:
1. ZK reports that it got started where in reality it failed with the following:
{noformat}
2011-05-24 10:18:58,217 - INFO [main:NIOServerCnxn$Factory@143] - binding to
port 0.0.0.0/0.0.0.0:2181
2011-05-24 10:18:58,219 - FATAL [main:ZooKeeperServerMain@62] - Unexpected
exception, exiting abnormally
java.net.BindException: Address already in use
{noformat}
2. It clobbers the zookeeper_server.pid file
