             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).
