As we've > discouraged users from using non-string partition column types, this presents > a problem for users who want to change there partition columns to be strings, > they have to rename their table, create a new table, and copy all the data > over. > To support this via the CLI, adding a command like ALTER TABLE <table_name> > PARTITION COLUMN (<column_name> <new type>); -- This message is automatically generated by JIRA.
