Flavio Junqueira commented on BOOKKEEPER-294: --------------------------------------------- Right, I should have looked more carefully at the log excerpt, it is about bookies not clients. If the znode still exists, then the session from the previous instance of the bookie hasn't expired. I don't see a problem right now with just deleting the znode if it still exists. > Not able to start the bookkeeper before the ZK session timeout. > --------------------------------------------------------------- > > Key: BOOKKEEPER-294 > URL: https://issues.apache.org/jira/browse/BOOKKEEPER-294 > Project: Bookkeeper > Issue Type: Bug > Reporter: Gopinathan A > Assignee: Rakesh R > > Not able to start the bookkeeper before the ZK session timeout. > Here i killed the bookie and started again. > {noformat} > 2012-06-12 20:00:25,220 - INFO [main:LedgerCache@65] - openFileLimit is 900, > pageSize is 8192, pageLimit is 456781 > 2012-06-12 20:00:25,238 - ERROR [main:Bookie@453] - ZK exception registering > ephemeral Znode for Bookie! > org.apache.zookeeper.KeeperException$NodeExistsException: KeeperErrorCode = > NodeExists for /ledgers/available/10.18.40.216:3181 > at org.apache.zookeeper.KeeperException.create(KeeperException.java:119) > at org.apache.zookeeper.KeeperException.create(KeeperException.java:51) > at org.apache.zookeeper.ZooKeeper.create(ZooKeeper.java:778) > at org.apache.bookkeeper.bookie.Bookie.registerBookie(Bookie.java:450) > at org.apache.bookkeeper.bookie.Bookie.<init>(Bookie.java:348) > at org.apache.bookkeeper.proto.BookieServer.<init>(BookieServer.java:64) > at org.apache.bookkeeper.proto.BookieServer.main(BookieServer.java:249) > {noformat} -- This message is automatically generated by JIRA.
