Peter Cseh commented on OOZIE-2780:
-----------------------------------

so I've run a depenency:tree -Dhadoop.version=2.7.0
When the hadoop component is referenced in our poms, the versions are correct.
Where the dependencies are only transitive, they'll stay at 2.6.0, mostly via 
hive-something:
{noformat}
 +- org.apache.hive.shims:hive-shims-0.23:jar:1.2.0:runtime
[INFO] |  |  |  |  \- 
org.apache.hadoop:hadoop-yarn-server-resourcemanager:jar:2.6.0:runtime
[INFO] |  |  |  |     +- org.apache.hadoop:hadoop-annotations:jar:2.6.0:runtime
,,,,
[INFO] |  |  |  |     +- org.apache.hadoop:hadoop-yarn-common:jar:2.6.0:runtime
[INFO] |  |  |  |     +- org.apache.hadoop:hadoop-yarn-api:jar:2.6.0:runtime
{noformat}
I don't think we can do too many things about this.

> Upgrade minimum Hadoop version to 2.6.0

> I'd like to contribute an fs action enhancement to modify extended attributes 
> to core but methods to change extended attributes is not available in 
> hadoop-common < 2.6.0. Currently hadoop-common is at 2.4. I am contributing a 
> patch to bump to 2.6 but so far I haven't been able to generate a clean test 
> as tests in core module fail randomly. On the first run, I had a failure on 
> {code} Failed tests:   
> testCheckAfterActionDelete(org.apache.oozie.service.TestHAPartitionDependencyManagerService):
>  Expected: <null> but was: [0000000-170123095541655-oozie-aerv-C@1]{code}
> and on second run
> {code}Failed tests:   testWaitFor(org.apache.oozie.test.TestXTestCase): 
> expected:<1000.0> but was:<2036.0>{code}
> I can't tell whether it is due to my patch?
