Code of Conduct

Search before asking

  • I have searched in the issues and found no similar issues.

What would you like to be improved?

When the shuffle server is deployed in the container, the memory keeps soaring until it exceeds the container's memory limit, and then the container is OOMKill. After checking the memory usage, it is found that there are a large number of 64 MB memory blocks.
Reference:
prestodb/presto#8993
https://issues.apache.org/jira/browse/HADOOP-7154

How should we improve?

In start-shuffle-server.sh, set MALLOC_ARENA_MAX(default cpu core * 8) to control memory application/usage
