IMPALA-5924: Improve formatting of TBLPROPERTIES in SHOW CREATE TABLE
When we run SHOW CREATE TABLE via Impala-shell output displays the
TBLPROPERTIES in a single line which makes it difficult to read
through all the properties.
Change:
Modified ToSqlUtils.java to wrap reconstructed TBLPROPERTIES into a
clean multi-line, indented layout instead of outputting them as a
single dense line.
Modified ToSqlTest.java to update the expected string assertions to
match the new multi-line format.
Example:
Before this change, TBLPROPERTIES were formatted on a single line in
SHOW CREATE TABLE output:
TBLPROPERTIES ('OBJCAPABILITIES'='HIVEMANAGEDINSERTREAD...', ...)
After this change, they are cleanly wrapped:
TBLPROPERTIES (
'OBJCAPABILITIES'='EXTREAD,EXTWRITE',
'TRANSLATED_TO_EXTERNAL'='TRUE',
'external.table.purge'='TRUE'
)
This improves the readability of generated DDL statements when
executing SHOW CREATE TABLE or viewing view definitions via
impala-shell.
Testing Performed:
- Updated expected string outputs in ToSqlTest.java to account for the
new whitespace layouts.
- Verified frontend changes compile cleanly using checkstyle.
- Ran mvn clean package -DskipTests (BUILD SUCCESS).
- Ran focus testing suite: mvn test -Dtest=ToSqlTest
(BUILD SUCCESS).
- Ran idempotency integrity validation suite:
mvn test -Dtest=ToSqlUtilsTest (BUILD SUCCESS).
