------------------------------------
Priority: Critical (was: Major)
> Add memory guard before decompressing queries in admissiond
> -----------------------------------------------------------
>
> Key: IMPALA-14763
> URL: https://issues.apache.org/jira/browse/IMPALA-14763
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Reporter: Yida Wu
> Assignee: Yida Wu
> Priority: Critical
>
> When admissiond is close to its memory limit and a very large query is
> dequeued, decompression (when compression is enabled) can push memory usage
> over the limit and cause OOM.
> We should add a protection similar to IMPALA-14493 to reject the queued query
> before decompression if current_memory + uncompressed_size > memory_limit.
