--------------------------------------------
Summary: Configurable DataXceiver thread stack size
Key: HDFS-4814
URL: https://issues.apache.org/jira/browse/HDFS-4814
Project: Hadoop HDFS
Issue Type: New Feature
Components: datanode
Reporter: Tsz Wo (Nicholas), SZE
Assignee: Tsz Wo (Nicholas), SZE
By default, Java creates a thread with 512kB stack size. In Datanode, we may
have 4096 or more DataXceiver threads. These threads do not require such large
stack size and unnecessarily occupy a large amount of memory.
