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. -- This message is automatically generated by JIRA.
