Mubarak Seyed commented on HBASE-4991:
--------------------------------------
@Stack
bq.This feature looks to be adding online merge to me. I need clarification
from Mubarak that that is indeed the case. If so, this issue is mislabeled and
the patch needs redoing.
Online merge requires table needs to be disabled but deleteRegion (deleteRange)
does not require table needs to be disabled.
We were discussing about making use of HMerge.merge() (please refer my comment
@ 27/Jan/12 06:36) but it checks for half of region-size
{code}
this.maxFilesize = conf.getLong(HConstants.HREGION_MAX_FILESIZE,
HConstants.DEFAULT_MAX_FILE_SIZE);
..
if ((currentSize + nextSize) <= (maxFilesize / 2)) {
// We merge two adjacent regions if their total size is less than
// one half of the desired maximum size
{code}
so, in this case an adjacent region size can be > half of max of region-size?
> Provide capability to delete named region
