Janaki Lahorani updated HIVE-17832:
-----------------------------------
Description: hive.metastore.disallow.incompatible.col.type.changes when set
to true, will disallow incompatible column type changes through alter table.
But, this parameter is not modifiable in HMS. If HMS in not embedded into HS2,
the value cannot be changed. (was:
hive.metastore.disallow.incompatible.col.type.changes when set to true, will
disallow incompatible column type changes through alter table. But, this
parameter is set system wide, and changing it requires restart of HMS. The
default value of this parameter is true. User can set the parameter to false
and change the column type through alter if this can be modified within a
session.)
