RaidNode should write temp files on /tmp and add random numbers to their names
to avoid conflicts
-------------------------------------------------------------------------------------------------
Key: MAPREDUCE-1659
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1659
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: contrib/raid
Affects Versions: 0.22.0
Reporter: Rodrigo Schmidt
Assignee: Rodrigo Schmidt
Fix For: 0.22.0
The RaidNode methods to raid files and recover them should write recovery and
tmp files on /tmp instead of /raid.
Besides that, filenames should have a random number appended to them to avoid
conflicts. This makes the code safer and avoids errors when multiple recoveries
run in parallel.
