Maryann Xue commented on PHOENIX-3394:
--------------------------------------
[~jamestaylor], looks like we need to make getSequence() into MetaDataClient
too.
Another thing is that we now have some necessary table resolving attempts. We
add a "phoenix" schema under the calcite root schema and set it as the default
schema. But still if a sql query refers to a table as "ATABLE" for
example,calcite will try resolving "phoenix" as a sub-schema (being
"phoenix.phoenix") under our default schema, which is the real "phoenix"
schema. And of course that sub-schema does not exist at all, but since Phoenix
lacks a way of querying a schema (when useNamespace = false), it will always
return a sub-schema object regardless. Thus afterwards there will be attempts
to resolve "phoenix.phoenix.ATABLE", which is gonna fail and then fall back to
"phoenix.ATABLE". [~julianhyde], this is what I saw from the debugger and have
no idea why.
