Ranjana Rajendran commented on HBASE-9741:
------------------------------------------
The test was written for the old balancer and took the default value in
defaults.xml which was 0.2f to prevent the stochastic balancer from searching
for a new base. With this value of 0.2f removed from defaults.xml, was then
taking the default value of 0.1f specified in the line ("float slop =
(float)UTIL.getConfiguration().getFloat("hbase.regions.slop", 0.1f);") which
made the test fail as this made the balancer search for a better fit which was
not the intention of this test.
I would like to understand why this test is required, i.e. why is this test
required to assert that regions are balanced using the function
assertRegionsAreBalanced() ? If this test need to be rewritten, I would like to
take up this task. Highly appreciate any input how to rewrite it different from
the patch above.
