Rohini Palaniswamy commented on OOZIE-1398:
-------------------------------------------
The first two are already taken care of. DB_VERSION used to be 1 for 3.2. This
patch does not contain it because it was done in OOZIE-1150.
{noformat}
if (ver.equals("1")) { // if db.version equals to 1 (after 3.2+), need to
upgrade
upgradeDBTo40(sqlFile, run, true);
}
else if (ver.equals(DB_VERSION)) { // if db.version equals to 2,
it's already upgraded
throw new Exception("Oozie DB has already been upgraded");
}
upgradeDBTo40() {
...
upgradeOozieDBVersion(sqlFile, run);
..
