The file was garbage collected later. The GC and Majc show that the file existed while the EOF happened. So this is probably either a bug in RFile fast skip or a bug related to the tablet closing. Probably related to the close w/ the close temporal relationship.

The security random walk test failed to drop a table.

The metadata tablet were being frequently loaded and unloaded as descried in ACCUMULO-329 when this happened.
The file in question was major compacted away on another tablet server. Shortly after this.

The file was garbage collected later. The GC and Majc show that the file existed while the EOF happened. So this is probably either a bug in RFile fast skip or a bug related to the tablet closing. Probably related to the close w/ the close temporal relationship.
