Subject [jira] [Commented] (HBASE-17575) Towards Making BASIC the Default In-Memory Compaction Policy
Date Thu, 02 Feb 2017 09:16:06 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17575?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15849690#comment-15849690

Eshcar Hillel commented on HBASE-17575:

Definitely we plan to run the same set of benchmarks we ran in HBASE-16417 over again. We
estimate we will see similar results.
We are using YCSB and not PE since it is more flexible and allows testing various workloads.

The current Jira is about adjusting the test environment towards the change in default.
Do you have any comments on the code?

> In preparation for switching the default in-memory compaction policy to BASIC, we would
like to make sure that once we do the switch all tests will run (and pass!) with the new default
> To this end, we remove the NONE configuration setting added to tests in HBASE-17294 and
> We verified these tests pass with all 3 memory compaction policies.
> For each test 
> (1) if all 3 policies pass the test -- we remove the configuration from the test.
> (2) if some fail we add tests of all 3 configurations, e.g., by parameterized tests.
When needed we update expected results.
> One test failure identified a small bug which is also fixed in the patch.
