-----------------------------------
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.
