Description

Performance evaluation gives a provision to pass the table name.
The table name is considered when we first initialize the table - like the disabling and creation of tables happens with the name that we pass.
But the write and read test again uses only the default table and so the perf evaluation fails.

I think the problem is like this

 ./hbase org.apache.hadoop.hbase.PerformanceEvaluation --nomapred --table=MyTable2  --presplit=70 randomRead 2

13/04/04 21:42:07 DEBUG hbase.HRegionInfo: Current INFO from scan results = {NAME => 'MyTable2,00000000000000000002067171,1365126124904.bc9e936f4f8ca8ee55eb90091d4a13b6.', STARTKEY => '00000000000000000002067171', ENDKEY => '', ENCODED => bc9e936f4f8ca8ee55eb90091d4a13b6,}
13/04/04 21:42:07 INFO hbase.PerformanceEvaluation: Table created with 70 splits

You can see that the specified table is created with the splits.
But when the read starts

Caused by: org.apache.hadoop.hbase.exceptions.TableNotFoundException: TestTable

It says TestTable not found which is the default table.
