Subject [jira] [Updated] (HADOOP-14003) Make additional KMS tomcat settings configurable
Date Wed, 25 Jan 2017 23:18:26 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-14003?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Andrew Wang updated HADOOP-14003:
    Attachment: HADOOP-14003.branch-2.003.patch

Here's one more rev. I realized that non-1 values of acceptorThreadCount requires the NIO
connector, so set the default to 1 and document this.

> Doing some Tomcat performance tuning on a loaded cluster, we found that {{acceptCount}},
{{acceptorThreadCount}}, and {{protocol}} can be useful. Let's make these configurable in
the kms startup script.
> Since the KMS is Jetty in 3.x, this is targeted at just branch-2.
