[jira] Commented: (HIVE-733) allow specifying maximum number of
serde exceptions to ignore

Namit Jain commented on HIVE-733:
---------------------------------
The parameter makes complete sense - in fact, traditional loader and querying tools (sql*loader etc.) support it
However, the parameter should be system wide and not specific to a mapper - you need to aggregate the counters
instead of looking at a single mapper.

+1
this makes sense, I'd set the default to larger than 0.
