-----------------------------------------------

Ya,  you are absolutely right.  Every time new PE object is getting created and that is the reason.

> 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}
