prakul agarwal commented on PHOENIX-3181:
-----------------------------------------

I'm using FailSafe parallel = method and threadCount ={5,10,50,100} to execute 
a bunch of test classes with forkCount = {2,3,4,5}. The integration-test phase 
is completing sometimes and getting stuck for long the other times. When it is 
getting stuck it is taking > 20 min than normal execution to complete.

In case when tests are getting stuck I notice that the log files 
(failsafe-reports folder) of individual test classes are generated each time 
consistently but the summary file generation does't happens for long. Also one 
surefire-booter jvm lingers on while others are killed.

When I execute in with forkCount = 1 the test execution probably doesnt start 
at all (Failsafe-reports folder is not generated, surefire tmp files are ). If 
I reduce the number of test classes to be executed (with forkCount = 1) then 
the execution is completing normally. 

I'm using reuseForks = true and have tried execution after removing all fork 
related settings.

Configuration:
Using Maven 3.3.9, maven-eclipse-plugin 2.9, failsafe 2.19.1, surefire 2.19.1.
OS name: "mac os x", version: "10.11.6", Intel 2.8 GHz i7, 16GB DDR3 RAM.
JDK 1.7.0_8

> With PHOENIX-3036, the tests within a test class can be executed in parallel 
> since the table names won't conflict. This should greatly reduce the time 
> taken to run all of our tests.
