Hello,
I am using hive-metastore jar version 1.2.1 and Hive version 2.3.2. I'd
like to make incompatible schema changes to my Hive tables.
The change I'm trying to make is to drop a column, which I am doing like
so: table.getSd().setCols(remaining_cols). I'm dropping an int column. The
column following it is a struct column, so my understanding is that it
assumes I'm trying to convert an int column to a struct column.
The error I get is:
InvalidOperationException(message:The following columns have types
incompatible with the existing columns in their respective positions...
Doing
ThriftHiveMetastore.Client client = new ThriftHiveMetastore.Client(
protocol);
client.get_config_value("hive.metastore.disallow.
incompatible.col.type.changes", "default_value");
gives me a true, which explains the failure earlier. How do I override this
value to false? Also, AFAICT the default value is supposed to be false, so
I'm not sure why this is returning true. I checked the hive-site.xml file
and it doesn't have this set.
Thanks for your help!
