> Key: IMPALA-12209
> URL: https://issues.apache.org/jira/browse/IMPALA-12209
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Gabor Kaszab
> Assignee: Dániel Gábor Vankó
> Priority: Major
> Labels: impala-iceberg, ramp-up
> Fix For: Impala 5.0.0
>
>
> Repro:
>
> {code:java}
> create table tmp (i int, s string) stored as iceberg tblproperties
> ('format-version'='2');
> describe extended/formatted tmp;
> show create table tmp;
> {code}
> Current behaviour:
> None of the following 2 commands contain 'format-version' in the output.
> Additionally, if you run what is returned from SHOW CREATE TABLE then you end
> up creating a V1 table instead of V2.
> The reason might be that format-version in the metadata.json is not stored
> within the tableproperties but it's on level above:
> {code:java}
> hdfs dfs -cat
> hdfs://localhost:20500/test-warehouse/tmp/metadata/00000-55bcfe84-1819-4fb7-ade8-9c132b117880.metadata.json
