Hi Impala community, I would like to contribute to Apache Impala by working on issues that I reported. Could you please grant me permission to assign Jira issues to myself?
My Apache Jira username: woosuk.ro I reported the following issues and would like to take ownership of them: 1. IMPALA-13112: Remove Kafka Dependency Exclusion from ranger-plugins-audit https://issues.apache.org/jira/browse/IMPALA-13112 Background: Previous versions of Impala excluded Kafka dependencies from ranger-plugins-audit to avoid JAX-RS conflicts. However, I've tested that kafka-clients-2.8.1.jar (used by current Apache Ranger) no longer causes these conflicts. Re-enabling Kafka dependencies is necessary for Ranger's kafkaAuditProvider to function properly for comprehensive audit logging. I've validated this in our production environment (Impala 4.4.0 + Hive 3.1.3) and am ready to prepare a patch with proper test cases. 2. IMPALA-14551: Query hangs when selecting an expression that contains Unicode Letters https://issues.apache.org/jira/browse/IMPALA-14551 I've identified the root cause: antlr-runtime 3.3 has a Unicode parsing bug that causes HiveLexer to enter an infinite retry loop during alias mapping when processing non-ASCII characters (e.g., Korean: 누적합, 매출액). Example query that hangs: select 누적합 - lag(누적합) over (partition by day order by day) from base Proposed fix: Upgrade antlr-runtime from 3.3 to 3.5.2 in fe/pom.xml I'm currently preparing comprehensive test cases with Korean, Japanese, and Chinese characters. Both issues have been validated in our production environment. I'm ready to submit patches via Gerrit and work with the community on reviews. Thank you for considering my request! Best regards, Woosuk Ro
