Owen O'Malley commented on HADOOP-1381:
---------------------------------------
I should also note that this would handle the current special case of the map
outputs that turn sync blocks off...
> The distance between sync blocks in SequenceFiles should be configurable
> rather than hard coded to 2000 bytes

> Currently SequenceFiles put in sync blocks every 2000 bytes. It would be much
> better if it was configurable with a much higher default (1mb or so?).
