-------------------------------

I think I have faced this issue with another combination. Not 2.2 on
Ubuntu14.04.
Can you check if there is a folder in hdfs (Try *hdfs dfs -ls /*) and see if
there is a folder there which is owned by user *ambari-qa*?
I do not remember the exact issue that I faced. The YARN service check failed
for me, and I noticed that there was no directory in hdfs that is owned by
*ambari-qa* user.

> I am new to Ambari. I installed ambari2.2 in ubuntu14.04 and deployed a
> cluster with HDFS, Mapreduce2, YARN, Hbase and Zookeeper in two nodes.
> Everything seems ok but when I ran service check of YARN though the web UI,
> it failed and reported timeout. Other service checks is ok. Any suggestion
> and guides will be welcome. Thanks!
