Aaron T. Myers commented on HADOOP-8121:
----------------------------------------
Thanks for checking on that, Natty. A few more comments/questions:
# Seems like we could cache the SearchControls object as well. Looks to me like it could even
just be statically initialized.
# I think createDirContext should be renamed getDirContext, as it's not necessarily creating
a new DirContext each time it's called.
# There's what looks to be a potential race in initializing the DirContext, since you check
for null and then initialize without holding any lock, though it may not matter at all.
# Since the DirContext is now long-lived, what happens if a connection to the LDAP server
breaks? Will this class automatically re-connect? (Is that even the right term?)
