Error says that it is caused by Write-Ahead Log located at ./state/local/snapshot was written using the class; cannot restore using org.wali.MinimalLockingWriteAheadLog

Bu i am not sure what does that mean?

Can someone help me here?

Thanks in Advance.

Hi, which NiFi version is that? Did you perform an upgrade previously? — andrew
Is it a clean install? Do you see this after a crash maybe? Trying to understand if there was any data in the pipeline before. And I would strongly recommend upgrading to the 0.6.1, current GA. — andrew
Yes. It is a clean install. I had downloaded tar file and extracted it. — Shashi
I wonder if this could be related to a Java runtime. What do you see when you run `java --version'? Make sure it's not some GCJ, but rather an Oracle JDK or OpenJDK, both 7 and 8 will work. Also, if you had no data in this instance, upgrade to 0.6.1 to pick up some fixes in this area, save some troubleshooting time. — andrew

This question is likely to be specific to the (now very old) 0.5 version of Nifi.

Based on the comment of @andrew the wrong JDK is the prime suspect.

What do you see when you run `java --version'? Make sure it's not some GCJ, but rather an Oracle JDK or OpenJDK, both 7 and 8 will work.
