Harsh J commented on HADOOP-1381:
---------------------------------
Yes, it would end up writing a marker after each record, as sync-writing
condition is checked after every record append.
> 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?).
