---------------------------------
Summary: MetaReader.tableExists should not return false if the
specified table regions has been split
Key: HBASE-7307
URL: https://issues.apache.org/jira/browse/HBASE-7307
Project: HBase
Issue Type: Bug
Affects Versions: 0.92.3, 0.96.0, 0.94.4
Reporter: rajeshbabu
Assignee: rajeshbabu
Fix For: 0.94.3, 0.92.2
If a region is split parent we are not adding it to META scan results during
full scan.
{code}
if (!isInsideTable(this.current, tableNameBytes)) return false;
if (this.current.isSplitParent()) return true;
// Else call super and add this Result to the collection.
super.visit(r);
{code}
If all regions of a table has been split then result size will be zero and
returning false.
{code}
fullScan(catalogTracker, visitor, getTableStartRowForMeta(tableNameBytes));
// If visitor has results >= 1 then table exists.
return visitor.getResults().size() >= 1;
{code}
Even table is present we are returning false which is not correct(its highly
possible in case of tables with one region).
