Commit Message:

PS5, Line 9: schema definition from schema definition
> what does that mean?
sorry... :-) I can delete the first "schema definition"

If a table is:

create table aa (c int) <-column definition
stored as AVRO
tblproperties('avro.schema.url'='xxxx')<- schema definition I referred to
or
tblproperties('avro.schema.literal'='xxxx')  <- schema definition I referred to

So impala preferred the later case.
