             Summary: Specify -Xms for tests
                 Key: HBASE-28135
                 URL: https://issues.apache.org/jira/browse/HBASE-28135
             Project: HBase
          Issue Type: Improvement
          Components: test
            Reporter: Istvan Toth
            Assignee: Istvan Toth


The default -Xmx value is JVM dependent, but the host memory size is usually 
included in the calculation.

-Xmx in turn is used to calculate some GC parameters, for example NewSize and 
OldSize, which affect the behaviour of tests.

As the memory consumption on the tests is not dependent on the host VM size, we 
could set -Xms for the tests explictly, and enjoy more consistent test results.
