Hi, we have NN HA on quorum Journal.

This problem is related only to HDFS service.
I did deploy client conf of MapReduce service. It updates client conf mapred-site.xml and hdfs-site.xml
I do see updated hdfs-site.xml
The other problem with HDFS service is that i can't DELETE any role (DN, Gateway, Journal node). Cloudera manager just starts to consume 100% cPU and jstack reports therad dead lock...

Vikram Srivastava helped me in google groups. Here is an explanation:
The alternatives priority for HDFS is by default configured lower than MapReduce, so deploying HDFS client configs only will not update what /etc/hadoop/conf points to.
