[jira] [Created] (IMPALA-7474) Tool to identify CPU bottlenecks

Anuj Phadke created IMPALA-7474:
-----------------------------------

             Summary: Tool to identify CPU bottlenecks
                 Key: IMPALA-7474
                 URL: https://issues.apache.org/jira/browse/IMPALA-7474
             Project: IMPALA
          Issue Type: Improvement
    Affects Versions: Impala 2.12.0
            Reporter: Anuj Phadke
            Assignee: Anuj Phadke


We run into a bunch of issues where we run impala into hangs or impacts query performance issues due to a very high CPU usage.
A tool which periodically collects stacks from impala (when enabled) and prints calls with high CPU usage would be very useful for debugging such issues. 
Running this tool should ideally incur a minimalistic overhead on impalad while collecting the stacks.
