Mahadev konar updated MAPREDUCE-3423:
-------------------------------------
Status: Open (was: Patch Available)
Bhallamudi,
Am not sure I get the changes in the second part of the patch:
{code}
- if (mapId == null || mapOutput == null) {
+ if (mapOutput == null) {
{code}
Also, the in the first part, wouldnt it be simpler if it was something like:
{code}
try{
} catch(IllegalArgument){
} catch (IOException) {
} catch(Exception) {
}
{code}
> Fetcher Thread should log proper exception
