It's a filesystem permissions problem.

@jasontedor File permissions have not been changed. When I look into this path E:\data\dc1elkprd\nodes\0\indices\application\_logs-2017.01.04\2\index\_3h9.cfe. I don't see the \_3h9.cfe file is that reason its failing, how can I fix it?

That would manifest as a `FileNotFoundException`.
