[jira] Created: (HBASE-2127) randomWrite mode of
PerformanceEvaluation benchmark program writes only to a small range of
keys
randomWrite mode of PerformanceEvaluation benchmark program writes only to a small range of keys
------------------------------------------------------------------------------------------------
Key: HBASE-2127
URL: https://issues.apache.org/jira/browse/HBASE-2127
Project: Hadoop HBase
Issue Type: Bug
Components: test
Affects Versions: 0.20.2
Environment: not relevant
Reporter: Kannan Muthukkaruppan
Priority: Minor
"randomWrite" mode of PerformanceEvaluation (PE), with nclients > 1, does random writes only within a small range rather than across all rows.
e.g, for:
./bin/hbase org.apache.hadoop.hbase.PerformanceEvaluation --nomapred --rows=1000 randomWrite 10
[Note: As per convention in all modes of PE, --rows is the number of rows per client]
So for the above, with # of clients set to 10, currently all clients generate writes to keys in the 0..999 range instead of the 0..9999 range.
[Fix appears to be simple. Will provide a patch.]
