Enis Soztutar created HBASE-7959:
------------------------------------
Summary: HBCK skips regions that have been recently modified,
which then leads to it to report holes in region chain
Key: HBASE-7959
URL: https://issues.apache.org/jira/browse/HBASE-7959
Project: HBase
Issue Type: Bug
Components: hbck
Reporter: Enis Soztutar
Fix For: 0.95.0, 0.98.0, 0.94.7
While lots of region splits going on, HBCK incorrectly reports inconsistencies
since it skips recently modified, but does not take those into account for
computing the region chain.
