> When scanning for a non existent table in hbase shell, error message in shell
> sometimes(based on META table content) displays completely unrelated table
> info , which seems to be unnecessary and inconsistent with other error
> messages:
> {noformat}
> hbase(main):016:0> scan 'noTable'
> ROW COLUMN+CELL
> ERROR: Unknown table Table 'noTable' was not found, got: hbase:namespace.!
> ---------------------------------------------------------------------------------------------
> hbase(main):017:0> scan '01_noTable'
> ROW COLUMN+CELL
> ERROR: Unknown table 01_noTable!
> --------------------------------------------------
> {noformat}
> Its happening when doing a META table scan (to locate input table ) and
> scanner stops at row of another table (beyond which table can not exist) in
> ConnectionManager.locateRegionInMeta:
> {noformat}
> private RegionLocations locateRegionInMeta(TableName tableName, byte[] row,
> boolean useCache, boolean retry, int replicaId) throws
> IOException {
> .................................
> ................................
> // possible we got a region of a different table...
> if (!regionInfo.getTable().equals(tableName)) {
> throw new TableNotFoundException(
> "Table '" + tableName + "' was not found, got: " +
> regionInfo.getTable() + ".");
> }
> ...............................
> ...............................
> {noformat}
> Here, we can simply put a debug message(if required) and just throw the
> TableNotFoundException(tableName) with only tableName instead of with
> scanner positioned row.
