Thomas D'Silva commented on PHOENIX-3870:
-----------------------------------------
This is failing because even though the server jar is 4.11, SYSTEM.CATALOG has
not yet been upgraded to 4.11, so the PARENT->CHILD view links are missing.
When we drop the base table, we check to see if there are any child views (by
searching for PARENT->CHILD links) and don't find any, so we allow the table to
be dropped (instead of throwing an exception since the drop table statement
didn't include CASCADE).
If SYSTEM.CATALOG has not yet been upgraded we should find the child views
using the CHILD->PARENT link.
[~jamestaylor] Whats the best way to figure out the version of SYSTEM.CATALOG ?
Should I load the PTable and lookup the timestamp?
