--------------------------------------
Summary: Large chunks during write can have memory pressure on DN
with multiple clients
Key: HDDS-2384
URL: https://issues.apache.org/jira/browse/HDDS-2384
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Rajesh Balamohan
During large file writes, it ends up writing {{16 MB}} chunks.
https://github.com/apache/hadoop-ozone/blob/master/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/keyvalue/KeyValueHandler.java#L691
In large clusters, 100s of clients may connect to DN. In such cases, depending
on the incoming write workload mem load on DN can increase significantly.
