Summary: Problem with HBCK mergeOverlaps
Key: HBASE-6331
URL: https://issues.apache.org/jira/browse/HBASE-6331
Project: HBase
Issue Type: Bug
Components: hbck
Reporter: Anoop Sam John
Assignee: Anoop Sam John
In HDFSIntegrityFixer#mergeOverlaps(), there is a logic to create the final
range of the region after the overlap.
I can see one issue with this code
{code}
if (RegionSplitCalculator.BYTES_COMPARATOR
.compare(hi.getEndKey(), range.getSecond()) > 0) {
range.setSecond(hi.getEndKey());
}
{code}
Here suppose the regions include the end region for which the endKey will be
empty, we need to get finally the range with endkey as empty byte[]
But as per the above logic it will see that any other key greater than the
empty byte[] and will set it.
Finally the new region created will not get endkey as empty byte[]
