> Project: HBase

> Affects Versions: 0.98.16
> Reporter: Lars Hofhansl
> Assignee: Alex Araujo
> Labels: mapreduce
> Fix For: 0.98.17

> We found that some of our copy table job run for many hours, even when there
> isn't that much data to copy.
> [~vik.karma] did his magic and found that the issue is with copying delete
> markers (we use raw mode to also move deletes across).
> Looking at the code in 0.98 it's immediately obvious that deletes (unlike
> puts) are not batched and hence sent to the other side one by one, causing a
> network RTT for each delete marker.
> Looks like in trunk it's doing the right thing (using BufferedMutators for
> all mutations in TableOutputFormat). So likely only a 0.98 (and 1.0, 1.1,
> 1.2?) issue.
