Lefty Leverenz commented on HIVE-6406:
--------------------------------------
Here's a Valentine nit for you in ErrorMsg.java:
bq. INSERT_INTO_IMMUTABLE_TABLE(10256, "Inserting into an non-empty immutable
table is not allowed"),
... should be "a non-empty" (also fix in insert_into5.q.out &
insert_into6.q.out).
And another in hive_metastore.thrift:
{quote}
+// Whether or not the table is considered immutable - immutable tables can
only be
+// overwritten or created if unpartitioned, or if partitioned, partitions
inside it
+// can only be overwritten or created. Immutability supports write-once and
replace
+// semantics, but not append.
{quote}
... "immutable tables" doesn't match "inside it" so change to "an immutable
table" (or "them").
> Introduce immutable-table table property and if set, disallow insert-into

> As part of HIVE-6405's attempt to make HCatalog and Hive behave in similar
> ways with regards to immutable tables, this is a companion task to introduce
> the notion of an immutable table, wherein all tables are not immutable by
> default, and have this be a table property. If this property is set for a
> table, and we attempt to write to a table that already has data (or a
> partition), disallow "INSERT INTO" into it from hive(if destination directory
> is non-empty). This property being set will allow hive to mimic HCatalog's
> current immutable-table property.
