Miguel Correia commented on ZOOKEEPER-780: ------------------------------------------ I've just picked a similar one so I guess the problem is more generic and has to do with the way zkCli.sh handles exceptions (i.e., misses handling some of them). This time I misspelled the parameter of the connect command (I forgot the ":"): Output: connect localhost2181 2010-05-25 11:28:25,241 - INFO [main:zookee...@538] - Session: 0x128cec5e35f0014 closed 2010-05-25 11:28:25,242 - INFO [main:zookee...@373] - Initiating client connection, connectString=localhost2181 sessionTimeout=30000 watcher=org.apache.zookeeper.zookeepermain$mywatc...@1bac748 Exception in thread "main" java.net.UnknownHostException: localhost2181 at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method) at java.net.InetAddress$1.lookupAllHostAddr(InetAddress.java:849) at java.net.InetAddress.getAddressFromNameService(InetAddress.java:1200) at java.net.InetAddress.getAllByName0(InetAddress.java:1153) at java.net.InetAddress.getAllByName(InetAddress.java:1083) at java.net.InetAddress.getAllByName(InetAddress.java:1019) at org.apache.zookeeper.ClientCnxn.<init>(ClientCnxn.java:383) at org.apache.zookeeper.ClientCnxn.<init>(ClientCnxn.java:328) at org.apache.zookeeper.ZooKeeper.<init>(ZooKeeper.java:377) at org.apache.zookeeper.ZooKeeperMain.connectToZK(ZooKeeperMain.java:261) at org.apache.zookeeper.ZooKeeperMain.processZKCmd(ZooKeeperMain.java:648) at org.apache.zookeeper.ZooKeeperMain.processCmd(ZooKeeperMain.java:581) at org.apache.zookeeper.ZooKeeperMain.executeLine(ZooKeeperMain.java:353) at org.apache.zookeeper.ZooKeeperMain.run(ZooKeeperMain.java:311) at org.apache.zookeeper.ZooKeeperMain.main(ZooKeeperMain.java:270) > zkCli.sh generates a ArrayIndexOutOfBoundsException > ----------------------------------------------------- > > Key: ZOOKEEPER-780 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-780 > Project: Zookeeper > Issue Type: Bug > Components: scripts > Affects Versions: 3.3.1 > Environment: Linux Ubuntu running in VMPlayer on top of Windows XP > Reporter: Miguel Correia > Priority: Minor > > I'm starting to play with Zookeeper so I'm still running it in standalone > mode.
