Zoltan Haindrich commented on HIVE-18191:
-----------------------------------------
[~mmccline]: I was expecting failures for the previous ticket(HIVE-18191) which
have fixed a small mistake; and have set the correct state of vectorization in
the TS operator.
Not gathering stats could have very bad consequences; I don't understand why
this doesn't surfaced earlier...stats gathering should be fixed; almost all of
the basic stats are depend on it.
I think the fact that this haven't surfaced earlier should be investigated;
because if I understand the inner workings of these things correctly: that
would mean that vectorization is off during all existing {{ANALYZE TABLE ...
COMPUTE STATISTICS}} calls ; which seems odd to me...
