stack commented on HBASE-19204:
-------------------------------

A 1.2 from May took less time, 3.58h rather than 6.3h (as reported by mvn).

real    238m5.507s
user    195m18.872s
sys     51m8.712s

Way less tests though Tests run: 1020, Failures: 11, Errors: 11, Skipped: 3... 
We are into second part. Lots of failure. Usual suspects.

Picking a few substantial, random tests and comparing run times:

May: Tests run: 4, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 453.85 sec 
- in org.apache.hadoop.hbase.regionserver.compactions.TestFIFOCompactionPolicy
Now: Tests run: 4, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 723.822 s 
- in org.apache.hadoop.hbase.regionserver.compactions.TestFIFOCompactionPolicy

May: Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 341.764 
sec - in org.apache.hadoop.hbase.snapshot.TestSnapshotClientRetries
Now: Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 293.96 s - 
in org.apache.hadoop.hbase.snapshot.TestSnapshotClientRetries

May: Tests run: 7, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 234.064 
sec - in org.apache.hadoop.hbase.TestMetaTableLocator
Now: Tests run: 7, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 233.968 s 
- in org.apache.hadoop.hbase.TestMetaTableLocator

May: Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 444.574 
sec - in org.apache.hadoop.hbase.regionserver.TestClusterId
Now: Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 442.794 s 
- in org.apache.hadoop.hbase.regionserver.TestClusterId

... test runs are about the same.

Checked the fork count and same between May and Now. Must be just number of 
tests then... Tip of 1.2 has latest surefire.

> Sean has been looking at tooling and infra. This Umbrellas is about looking 
> at actual tests. For example, running locally on dedicated machine I picked a 
> random test, TestPerColumnFamilyFlush. In my test run, it wrote 16M lines. It 
> seems to be having zk issues but it is catching interrupts and ignoring them 
> ([~carp84] fixed this in later versions over in HBASE-18441).
> Let me try and do some fixup under this umbrella so we can get a 1.2.7 out 
> the door.
