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

bq. Do you still look for the cryptic JVM version?

Good stuff [~chia7712] You've seen HDFS-12711? It is about some (or various) 
items in hdfs that are blowing up tests. 

As you can tell I put the investigation aside. Seems like its back again with a 
vengeance. But how comes when I build locally w/ jdk8_73 I see timeouts (have 
not checked if they are same as the type you identify above ... I see similar 
looking timeouts on branch-2 builds... 
https://builds.apache.org/job/HBase%20Nightly/job/branch-2/119/artifact/output-jdk8/patch-unit-root.txt)?

The old style 1.2 build is broke. 
https://builds.apache.org/view/H-L/view/HBase/job/HBase-1.2-JDK7/ It is using 
the 'latest' jdk7 available. The nightly jdk7 1.2 build is using  1.7.0_151 
(one of the hangling jdk7s going by your finding above) and Apache Maven 3.0.5. 
/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java The last good nightly failed the 
hbase-server second part tests with timeouts... 
https://builds.apache.org/job/HBase%20Nightly/job/branch-1.2/131/artifact/output-jdk7/patch-unit-root.txt

Possible to compile w/ 1.7 but run w/ 1.8 [~busbey]? Our yetus probably doesn't 
allow this?

> 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.
