Changing this idle timeout seems like a good idea to me. As @ayushtkn
mentioned, I think you have accidentally included "Bump Jetty Version" too in
this PR.
Do we also need to update the various *-site.xml files? I see this parameter
mentioned here, and always as 1 second:
```
$ grep -R -A1 "hadoop.http.idle_timeout.ms" *
hadoop-common-project/hadoop-common/src/main/resources/core-default.xml:
<name>hadoop.http.idle_timeout.ms</name>
hadoop-common-project/hadoop-common/src/main/resources/core-default.xml-
<value>1000</value>
--
hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/http/HttpServer2.java:
"hadoop.http.idle_timeout.ms";
hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/http/HttpServer2.java-
public static final int HTTP_IDLE_TIMEOUT_MS_DEFAULT = 10000;
--
hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/CommonConfigurationKeysPublic.java:
"hadoop.http.idle_timeout.ms";
hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/CommonConfigurationKeysPublic.java-
public static final int HADOOP_HTTP_IDLE_TIMEOUT_MS_DEFAULT = 1000;
--
hadoop-common-project/hadoop-kms/src/main/resources/kms-default.xml:
<name>hadoop.http.idle_timeout.ms</name>
hadoop-common-project/hadoop-kms/src/main/resources/kms-default.xml-
<value>1000</value>
--
hadoop-hdfs-project/hadoop-hdfs-httpfs/src/main/resources/httpfs-default.xml:
<name>hadoop.http.idle_timeout.ms</name>
hadoop-hdfs-project/hadoop-hdfs-httpfs/src/main/resources/httpfs-default.xml-
<value>1000</value>
```
Note it is also mentioned on CommonConfigurationKeysPublic.java and
HttpServer2.java as well as the *-site.xml file. Its a bit confusing for it to
be mentioned in so many places.
Should HttpServer2 reference the constant and default in
CommonConfigurationKeysPublic instead?
