>                 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
>            Priority: Major
>              Labels: supportability

> 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.
