Work Description: marton-bod opened a new pull request #1797:
URL: https://github.com/apache/hive/pull/1797
### What changes were proposed in this pull request?
Add new config option to set a default storage handler class. If this config
is set to a valid, existing class, the storage handler class won't have to be
explicitly provided in the create table statement with the `STORED BY `clause,
but will be 'inserted' under the hood.
For example, if
`hive.default.storage.handler.class=org.apache.iceberg.mr.hive.HiveIcebergStorageHandler`
is set,
then the command `CREATE TABLE abc (a int, b string) LOCATION ...` will be
equivalent to
`CREATE TABLE abc (a int, b string) STORED BY
'org.apache.iceberg.mr.hive.HiveIcebergStorageHandler' LOCATION ...`
### Why are the changes needed?
In order to use existing create table commands for new table formats, such
as Iceberg, without modification.
### Does this PR introduce _any_ user-facing change?
new config option settable via beeline/hive-site
### How was this patch tested?
q tests + manually with local run

> Add a config param "hive.default.storage.handler.class" so we can set a
> default storage handler class that can be used for all create table
> statements. By default it would be an empty string, taking no effect.
> This would allow existing user queries to be reused for a new table format
> for example, such as Iceberg.
> For example, after setting in the config: hive.default.storage.handler.class=
> org.apache.iceberg.mr.hive.HiveIcebergStorageHandler
> The query: CREATE TABLE abc (a int, b string) LOCATION ...
> would be equivalent to: CREATE TABLE abc (a int, b string) STORED BY
> 'org.apache.iceberg.mr.hive.HiveIcebergStorageHandler' LOCATION ...
