Harsh J commented on HADOOP-1381:
---------------------------------
Todd,
- The sync _interval_ can be arbitrary I think, can even be 0. Should not be
negative, so I'll add a check for that instead. Or do you think its better if
we limit the interval to a minimum? Writer tests pass with 0 no problem.
- SYNC_INTERVAL is being used by MAPREDUCE right now, and I'll have to carry
this out as a cross-project JIRA+patch.
> 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?).
