Istvan Toth updated HBASE-28135:
--------------------------------
Description:
The default -Xms value is JVM dependent, but the host memory size is usually
included in the calculation.
-Xms 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.
