Hello Quanlong Huang, Riza Suminto, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/23536
to look at the new patch set (#2).
Change subject: IMPALA-13066: Extend SHOW CREATE TABLE to include stats and
partitions
......................................................................
IMPALA-13066: Extend SHOW CREATE TABLE to include stats and partitions
- Add a new "WITH STATS" option to SHOW CREATE TABLE
- When WITH STATS is specified:
* Emit ALTER … ADD PARTITION … ; clauses for existing partitions
* Emit ALTER … SET TBLPROPERTIES for table-level stats (numRows,
STATS_GENERATED_VIA_STATS_TASK, etc.)
* Emit ALTER … SET COLUMN STATS for each column (numDVs, numNulls, maxSize,
avgSize)
- Update parser, analyzer, and frontend plan to handle the new option
- Add tests to verify correct generation of partition/stat statements
- Ensure backward compatibility: default behavior of SHOW CREATE TABLE remains
unchanged
