Description
Hello,
I'm trying to install and run dr elephant. I have successfully compiled and got the zip file. However, when I run the start.sh the message shows Dr.elephant started but does nothing.
I have attached the error screenshot of dr.log.
My Dr Elephant web UI doesn't open. nothing shows up.
Please help me..
Thanks
Mohan.P

Research direction
Start by reviewing the reported start.sh invocation and the attached dr.log screenshot for the TezFetcher class error, then inspect how Dr. Elephant starts its web UI. Reproduce the installation and startup flow in a comparable Hadoop environment; done means the service starts without this error and the web UI opens.
