When you try to view file from HWI , you get error with "HTTP ERROR 500" and stacktrace for JSP file. It says that "Unable to compile class for JSP file"

Here are the details for stacktrace :-

I have used below configuration :-

<property>
<name>hive.hwi.listen.host</name>
<value>localhost</value>
<description>This is the host address the Hive Web Interface will listen on</description>
</property>
<property>
<name>hive.hwi.listen.port</name>
<value>9999</value>
<description>This is the port the Hive Web Interface will listen on</description>
</property>
<property>
<name>hive.hwi.war.file</name>
<value>/lib/hive-hwi-0.11.0.war</value>
<description>This sets the path to the HWI war file, relative to ${HIVE_HOME}. </description>
</property>

Note :- I have used hwi-0.11.0.war , as 'war' file for HWI is not available in tar file(1.2.1 version) , also i can't complie code in local to generate it.
