HBaseAdmin.tableExists() should not require a full meta scan
------------------------------------------------------------
Key: HBASE-2857
URL: https://issues.apache.org/jira/browse/HBASE-2857
Project: HBase
Issue Type: Improvement
Reporter: Jonathan Gray
Fix For: 0.90.0
HBaseAdmin.tableExists() actually makes a call to HBaseAdmin.listTables() and
then checks if the table you are looking for is in the list.
listTables() uses a MetaScanner/MetaVisitor, thus requiring an entire META
table scan.
We should not require a full META scan to check for the existence of a single
table.
