Ankit Singhal commented on HBASE-22777:
---------------------------------------
bq. my test is failing. Need to figure why (I ask to merge 5 but it is doing 2
still...). Let me see what else I've broke.
Just skimmed the patch and I think , it may be because of this typo, shouldn't
it be highestEndKey instead of lowestStartKey.
{code}
+ if (highestEndKey == null) {
+ highestEndKey = ri.getEndKey();
+ } else if (ri.isLast() || Bytes.compareTo(ri.getEndKey(),
lowestStartKey) > 0) {
+ highestEndKey = ri.getEndKey();
+ }
{code}
Will also give it a try to test this patch tomorrow and share my feedback.
> Add a multi-region merge (for fixing overlaps, etc.)

> MergeTableRegionProcedure does two regions at a time only. We have hardcoded
> notion that merge has an 'A' and 'B' parent.
> This issue is about making it so we merge N regions all in the one go. We
> need this facility generally; will simplify operator's life being able to
> merge up in one go rather than in steps of two. In particular, would make
> fixing overlaps easier if could just merge all regions in the overlapping
> area.
