yuemeng updated ZOOKEEPER-2375:
-------------------------------
Description:
If there are exist many ZooKeeperSaslClient instance in one process,each
ZooKeeperSaslClient instance will be call synchronize method
createSaslClient,But each ZooKeeperSaslClient instance will be lock the current
object(that is say ,the synchronize only for lock it's own object) ,but many
instances can access the static variable login,the synchronize can't prevent
other threads access the static login object,it will be cause more than one
ZooKeeperSaslClient instances use the same login object,and
login.startThreadIfNeeded() will be called more than one times for same thread
object。
it wll cause problem:
ERROR | [Executor task launch worker-1-SendThread(fi1:24002)] | Exception
while trying to create SASL client: java.lang.IllegalThreadStateException |
org.apache.zookeeper.client.ZooKeeperSaslClient.createSaslClient(ZooKeeperSaslClient.java:305)
