Ted Yu commented on HBASE-12223:
--------------------------------
{code}
+ TableName tableName = TableName.valueOf(Bytes.toBytes(tableNameStr));
{code}
Why not let tableMaps be keyed by TableName ?
{code}
regionLocator = conn.getRegionLocator(tableName);
regionLocator = (RegionLocator) table;
{code}
The first assignment above can be removed.
> MultiTableInputFormatBase.getSplits is too slow
