[I] HUDI Experiences Significant Delays When Initializing ServiceabilityAgentSupport with Velox Enabled [hudi]

["hudi-bot (via GitHub)" <gi...@apache.org>]

hudi-bot opened a new issue, #16377:
URL: https://github.com/apache/hudi/issues/16377

   The current version of HUDI, when Velox (a C++ component) is enabled, uses ObjectSizeCalculator.getObjectSize, which triggers the initialization of ServiceabilityAgentSupport (in singleton mode, initialization occurs on the first call). During this process, the execution of the needSudo method takes approximately 50 seconds. If we restart a pod with Spark each time, it results in a significant delay, which is a critical issue. Although it's possible to bypass this by setting the JVM parameter -Djol.skipHotspotSAAttach=true, this workaround requires additional configuration to restore normal operation. Is this still considered an unexpected behavior?
   
   Here's the private constructor for ServiceabilityAgentSupport:
   
    
   {code:java}
   private ServiceabilityAgentSupport() {
       processId = getCurrentProcId();
       agentStyle = senseAgentStyle();
       sudoRequired = needSudo(agentStyle);
   }
    {code}

   This issue was reviewed as part of the JIRA-migrated backlog triage (HUDI-7329).
   
   **Findings: still open.**
   
   No commit on `master` references HUDI-7329, so nothing has landed under this ticket's key.
   
   The description is substantive and self-describing, so this is workable as written - what is missing is an owner rather than a specification.
   
   Keeping this open.
