[1/3] kudu git commit: KUDU-1544: Race in Java client's
AsyncKuduSession.apply()
Repository: kudu
Updated Branches:
refs/heads/master faa0b14ef -> 1c70e5df8
KUDU-1544: Race in Java client's AsyncKuduSession.apply()
This fixes a potential race in AsyncKuduSession.apply by acquiring the
notification deferred early. See the JIRA for details about the race.
Acquiring the notification deferred early is always safe, the only
downside is that clients may be spuriously notified that there is buffer
space available when in fact there is not.
