What is the importance of Tomcat server references in Hadoop package ?

[#1]

@Sai Sankar

Can you please elaborate your query a bit more.

Following are some old references of Tomcat+Hadoop JIras:
There are some JIRAs where we see "httpfs" switch from Tomcat to Jetty like: https://issues.apache.org/jira/browse/HDFS-10860
Also please see : https://issues.apache.org/jira/browse/HADOOP-13812 (Upgrade Tomcat for hadoop)

Similarly for Hadoop KMS tomcat weak cipher issue: https://issues.apache.org/jira/browse/HADOOP-14083
