Tim Armstrong commented on IMPALA-7208:
---------------------------------------
I was able to run it on a release build but the cluster was basically idle.
> Consider using quickstack instead of pstack

> Key: IMPALA-7208
> URL: https://issues.apache.org/jira/browse/IMPALA-7208
> Project: IMPALA
> Issue Type: Improvement
> Components: Infrastructure
> Reporter: Tim Armstrong
> Priority: Major
> Labels: supportability
> Attachments: quickstack.out

> This is an alternative to heavyweight methods like pstack and gdb that can
> block the process while they're collecting stacks:
> https://github.com/yoshinorim/quickstack . Yoshinori has a lot of experience
> troubleshooting production systems so his recommendation carries some weight
> for me.
> I tried it out and it seems to work as advertised so far. The binary is
> pretty small and easy to build so isn't an unreasonable dependency.
