Wrap OBS data access queries with retry(5, 3000) to mitigate cross-region network instability between Alibaba Cloud Hong Kong test machines and Huawei Cloud OBS Beijing endpoint (obs.cn-north-4.myhuaweicloud.com). The Connect timed out / RequestTimeOut (408) errors from ObsException are transient and retryable. Co-Authored-By: Claude <noreply@anthropic.com>

Problem
Paimon filesystem catalog OBS queries intermittently fail with
Connect timed out/RequestTimeOut (408)errors.Root cause: test machines are in Alibaba Cloud Hong Kong, while the OBS endpoint is
obs.cn-north-4.myhuaweicloud.com(Beijing). Cross-region network instability causes transient TCP connection failures.Related: DORIS-26713
Solution
Add
retry(5, 3000)(5 attempts, 3s interval) around OBS data access queries inpaimon_base_filesystem.groovy:show databases,use, SELECT queries blockqt_obs obscomparison calls (force_jni_scanner=false and true)The retry uses the existing framework
Suite.retry()method which catches any Throwable and re-executes the closure. Network errors from OBS will be retried transparently.OSS/COS/COSN operations are unaffected as they use different endpoints.
