[jira] [Commented] (IMPALA-4052) CREATE TABLE LIKE for Kudu tables

    [ https://issues.apache.org/jira/browse/IMPALA-4052?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17555373#comment-17555373 ]

-----------------------------------

Hi [~dtsirogiannis], I want to fix this issue, is there a blocking problem that prevents us from implementing CREATE TABLE LIKE for Kudu tables?

>             Project: IMPALA
>          Issue Type: Improvement
>          Components: Catalog
>    Affects Versions: Impala 2.7.0

> 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
