Ted Yu commented on HBASE-3421:
-------------------------------
Patch v2 looks good.
Minor comment: 10 should be replaced with new config below:
{code}
+ // Limit this to 10 to avoid OOME
{code}
The patch doesn't apply on TRUNK.
Please prepare another patch for 0.92/TRUNK.
Thanks
> Very wide rows -- 30M plus -- cause us OOME

> From the list, see 'jvm oom' in
> http://mail-archives.apache.org/mod_mbox/hbase-user/201101.mbox/browser, it
> looks like wide rows -- 30M or so -- causes OOME during compaction. We
> should check it out. Can the scanner used during compactions use the 'limit'
> when nexting? If so, this should save our OOME'ing (or, we need to add to
> the next a max size rather than count of KVs).
