------------------------------------
Summary: Port range binding fails due to socket bind race condition
Key: HADOOP-15897
URL: https://issues.apache.org/jira/browse/HADOOP-15897
Project: Hadoop Common
Issue Type: Bug
Components: ipc
Affects Versions: 2.0.2-alpha
Reporter: Daryn Sharp
Assignee: Daryn Sharp
Java's {{ServerSocket#bind}} does both a bind and listen. At a system level,
multiple processes may bind to the same port but only one may listen. Java
sockets are left in an unrecoverable state when a process loses the race to
listen first.
Servers that compete over a listening port range (ex. App Master) will fail the
entire range after a collision. The IPC layer should make a better effort to
recover from failed binds.
