------------------------------
Yeah... should be ok now. Thanks for the patch.
> Let PerformanceEvaluation support setting tableName and compress algorithm

> Issue Type: Improvement
> Components: test
> Affects Versions: 0.20.1

> 1. Current PerformanceEvaluation.java defaultly does not use compression, and
> always use table name as "TestTable". Tow comand- arguments are added to
> support setting tableName and compression algorithm by user. e.g.:
> (1) tableName="PE_LZO", compression="lzo"
> bin/hbase org.apache.hadoop.hbase.PerformanceEvaluation --table=PE_LZO
> --compress=lzo sequentialWrite 4
> (2) default (tabmeName="TesTable", compression="none"
> bin/hbase org.apache.hadoop.hbase.PerformanceEvaluation sequentialWrite 4
> 2. Current "public static byte[] generateValue(final Random r)" generates
> bytes[] which is too random. So the effect of compression is not obvious
> (e.g. there is not size reduce for LZO).
> A new "public static byte[] generateValue(final Random r)" is provided here.
> We can get 4:1 compression ratio for LZO now.
