Subject [jira] [Updated] (HADOOP-14347) Make KMS and HttpFS Jetty connection backlog configurable
Date Tue, 25 Apr 2017 22:01:04 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-14347?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

John Zhuge updated HADOOP-14347:
    Attachment: HADOOP-14347.002.patch

Patch 002
* HttpServer2 reads a new property {{hadoop.http.accept.queue.size}} and sets the connection
backlog. The property default is 128 which is the current hard-coded value.
* Add  {{hadoop.http.accept.queue.size}} with default 128 to core-default.xml
* Refactor core-default.xml, kms-default.xml, and httpfs-default.xml
** Create a section {{HTTP properties}} in core-default.xml, add related {{hadoop.http.*}}
properties there. The default values match those in HttpServer2.
** kms-default.xml only maintains KMS overrides, e.g., max thread is 1000, accept queue size
is 500, matching the Tomcat values in branch-2.
** httpfs-default.xml only maintain HttpFS overrides, e.g., max threads is 150, matching the
Tomcat value in branch-2.

> HADOOP-14003 enabled the customization of Tomcat attribute {{protocol}}, {{acceptCount}},
and {{acceptorThreadCount}} for KMS in branch-2. See https://tomcat.apache.org/tomcat-6.0-doc/config/http.html.
> KMS switched from Tomcat to Jetty in trunk. Only {{acceptCount}} has a counterpart in
Jetty, {{acceptQueueSize}}. See http://www.eclipse.org/jetty/documentation/9.3.x/configuring-connectors.html.
