Mubarak Seyed commented on HBASE-4991:
--------------------------------------
I think we can make use of
{code}
protected boolean merge(final HRegionInfo[] info) throws IOException {
if ((currentSize + nextSize) <= (maxFilesize / 2)) {
// We merge two adjacent regions if their total size is less than
// one half of the desired maximum size
LOG.info("Merging regions " + currentRegion.getRegionNameAsString() +
" and " + nextRegion.getRegionNameAsString());
HRegion mergedRegion =
HRegion.mergeAdjacent(currentRegion, nextRegion);
updateMeta(currentRegion.getRegionName(), nextRegion.getRegionName(),
mergedRegion);
break;
}
}
{code}
what happens if sum(previous_region_size and next_region_size ) > maxFileSize
when we try to merge adjacent regions (to bridge the hole)?
