[jira] [Created] (HDDS-2653) Improve executor memory usage in new
Freon tests
Attila Doroszlai created HDDS-2653:
--------------------------------------
Summary: Improve executor memory usage in new Freon tests
Key: HDDS-2653
URL: https://issues.apache.org/jira/browse/HDDS-2653
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Components: freon
Affects Versions: 0.5.0
Reporter: Attila Doroszlai
Assignee: Attila Doroszlai
New Freon tests (descendants of {{BaseFreonGenerator}}) suffer from a similar memory issue due to concurrency handling as HDDS-1785.
Steps to reproduce:
{{code}}
export HADOOP_OPTS='-Xmx256M -XX:+HeapDumpOnOutOfMemoryError'
ozone freon omkg -F ONE -n 33554432 -t 10 -p omkg
{code}
Freon attempts to submit 32M tasks to the executor, requiring at least 1.5GB memory.
