[jira] [Updated] (HADOOP-15638) KMS Accept Queue Size default
changed from 500 to 128 in Hadoop 3.x

-------------------------------------
Component/s: kms
> KMS Accept Queue Size default changed from 500 to 128 in Hadoop 3.x
> -------------------------------------------------------------------
>
> Key: HADOOP-15638
> URL: https://issues.apache.org/jira/browse/HADOOP-15638
> Project: Hadoop Common
> Issue Type: Bug
> Components: kms
> Affects Versions: 3.0.0-alpha2
> Reporter: Wei-Chiu Chuang
> Priority: Major
>
> HADOOP-13597 migrated KMS from Tomcat to Jetty.
> In Hadoop 2.x, the Accept Queue Size default value was set by environment variable KMS_ACCEPT_QUEUE with default value 500.
> But after the migration, Hadoop 3.x now uses the default HttpServer2 configuration to set accept queue size (hadoop.http.socket.backlog.size), which is 128.
> Should we restore the default accept queue size in kms-default.xml? Should we document it as a known issue? After all, Hadoop 2 --> 3 allows breaking changing.
