IMPALA-4052: CREATE TABLE LIKE for Kudu tables
This commit implements cloning between Kudu tables, including clone the
schema and hash partitions. But there is one limitation, cloning of
Kudu tables with range paritions is not supported. For cloning range
partitions, it's tracked by IMPALA-11912.
Cloning Kudu tables from other types of tables is not implemented,
because the table creation statements are different.
Testing:
- e2e tests
- AnalyzeDDLTest tests

> Components: Catalog
> Affects Versions: Impala 2.7.0
> Reporter: Dimitris Tsirogiannis
> Assignee: gaoxiaoqing
> Priority: Major

>
> The semantics of CREATE TABLE LIKE when Kudu tables are involved, either as a
> source or as a target table, are not well specified or properly implemented;
> in some cases a misleading ImpalaRuntimeException is thrown.
> Actions:
> # Decide whether CREATE TABLE LIKE will be supported for Kudu tables.
> # Implement whatever approach is decided
> # Properly document both in Impala and Kudu docs the supported operations
