zabetak opened a new pull request, #4545:
URL: https://github.com/apache/hive/pull/4545
Without these changes the parser consumes fully the input string and if the
input does not match exactly the expected pattern null is returned.
However there are cases where the input string starts with a completely
valid date that matches the pattern but then it is followed by other
characters; for example timestamps.
The `DateParser` can handle `2023-08-03T16:02:00` but will return null for
`2023-08-03_16:02:00`. Interestingly, it also handles fine `2023-08-03TGARBAGE`
but not `2023-08-03_GARBAGE`.
With these changes the `DateParser` can now extract valid dates even if
there are trailing invalid chars after the expected pattern.
The changes restore backward compatibility when parting dates since partial
parsing used to work before HIVE-20007. At the same time, it makes parsing more
uniform since we do not treat 'T' or space (' ') as special cases and
simplifies the parsing code.
