Hi all,
I had a running topology and then I changed a component of it by adding
additional member variable to one of the components to store the task
iD(private int taskId).
After making this change and submitting the Jar i get the following error.
When I remove this variable every things starts to work fine.
I'm using version 0.9.1-incubating. I tried clearing storm-local
directories of both supervisor and nimbus but it didn't work.
Can someone please give some idea to fix this issue.
