---------------------------------------------
Summary: Performance Evaluation does not consider the table name
passed in the argument
Key: HBASE-8279
URL: https://issues.apache.org/jira/browse/HBASE-8279
Project: HBase
Issue Type: Bug
Reporter: ramkrishna.s.vasudevan
Assignee: ramkrishna.s.vasudevan
Priority: Minor
Fix For: 0.95.0, 0.98.0, 0.94.7
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
{code}
./hbase org.apache.hadoop.hbase.PerformanceEvaluation --nomapred
--table=MyTable2 --presplit=70 randomRead 2
{code}
{code}
13/04/04 21:42:07 DEBUG hbase.HRegionInfo: Current INFO from scan results =
{NAME =>
'MyTable2,00000000000000000002067171,1365126124904.bc9e936f4f8ca8ee55eb90091d4a13b6.',

13/04/04 21:42:07 INFO hbase.PerformanceEvaluation: Table created with 70 splits
{code}
You can see that the specified table is created with the splits.
But when the read starts
{code}

It says TestTable not found which is the default table.
