Alan Gates commented on PIG-166:
--------------------------------
Based on Pi's observation that deleteOnExit is too lazy and we delete the bag
spill files much sooner (when the bag is finalized), I checked the code, and we
are already doing that. The DataBag.finalize() method walks the list of spill
files and deletes them.

> URL: https://issues.apache.org/jira/browse/PIG-166
> Project: Pig
> Issue Type: Bug
> Reporter: Amir Youssefi
>
> Occasionally spilling fills up (all) hard drive(s) on a Data Node and crashes
> Task Tracker (and other processes) on that node. We need to have a safety net
> and fail the task before crashing happens (and more).
> In Pig + Hadoop setting, Task Trackers get Black Listed. And Pig console gets
> stock at a percentage without returning nodes to cluster. I talked to Hadoop
> team to explore Max Percentage idea. Nodes running into this problem get into
> permanent problems and manual cleaning by administrator is necessary.
