This issue was reviewed as part of the JIRA-migrated backlog triage.
Findings: This appears to be fixed by #7342 (HUDI-5302, merged 2022-12-03),
with further hardening in #12120 (HUDI-8403). The naive recordKey.split(",")
shown in the report no longer exists;
BucketIdentifier.getHashKeysUsingIndexFields (BucketIdentifier.java:52-53) now
delegates to KeyGenUtils.extractRecordKeysByFields, which parses complex keys
by searching for the record-key separator in reverse so comma-containing values
are handled. Covered by TestKeyGenUtils.testExtractRecordKeys.
If you're still hitting this on a recent version, please reopen with repro
steps.
Verified on Hudi 1.2.0 (Spark 3.4): a bucket-index table with record-key
values containing commas upserts and reads back correctly (no duplicate,
correct update), confirmed with a reproducer.
Closing as fixed.
