Let PerformanceEvaluation support setting tableName and compress algorithm
--------------------------------------------------------------------------
Key: HBASE-1902
URL: https://issues.apache.org/jira/browse/HBASE-1902
Project: Hadoop HBase
Issue Type: Improvement
Components: test
Affects Versions: 0.20.1
Reporter: Schubert Zhang
Assignee: Schubert Zhang
Priority: Minor
Fix For: 0.21.0
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.
