Samarth Jain updated PHOENIX-1172:
----------------------------------
Attachment: PHOENIX-1172-3.0-v2.patch
v2 patch for 3.0 branch. It gets rid of the locking on metadata since it is ok
for a thread to work off a stale copy of metadata when establishing a
connection or other operations that just do a read from it. Writes to metadata
are still guarded by a lock.
Also, the exception handling has been simplified to wrap every exception thrown
during init into a SQLException (if it isn't already a SQLException)
[~jamestaylor] - The patch is for 3.0 branch. If it looks good, I will generate
separate patches for 4.0 and master branches.
> Prevent lock contention in ConnectionQueryServicesImpl. Fix exception
> handling.
