-----------------------------------
Summary: hbase performance evaluation tool could not support
datasize more than 2048g
Key: HBASE-26017
URL: https://issues.apache.org/jira/browse/HBASE-26017
Project: HBase
Issue Type: Bug
Components: PE
Affects Versions: 2.4.4, 2.3.2, 2.1.0
Reporter: dingwei2019
in our daily test, we may hope to test more datasize than 2048g, when we set
--size more than 2048g, pe print abnormal message like this:
[TestClient-1] hbase.PerformanceEvaluation: Start class
org.apache.hadoop.hbase.PerformanceEvaluation$SequentialWriteTest at offset
-1138166308 for -21474836 rows
this is due to variable totalRows in TestOptions defined by int(-2147483648
--- 2147483647), One GB is 1048576(1024*1024) by default. The max value of
totalRow is 2147483647, in this condition, we may write not larger than
2147483647/1048576 = 2047.999G.
