I have a cluster of two machines and using apache hbase and apache hadoop. I have to use hue so that I can interect with hbase or hdfs through GUI. I have installed it successfully on my machine(ubuntu 14.04) but it is showing nothing about hdfs or tables etc. and gives error like
1.oozie server is not running
2.could not connect to local:9090
HBase thrift server cannot be contacted
How to do setting og hue so that it should connect to my running cluster.

I have hadoop 3.1.2 and hive 3.1.2 on a cluster and I want to connect to hive with presto-server-0.265.1.
I have just one catalog file in /opt/presto/etc/catalog as hive.properties here is:
connector.name=hive-hadoop2
hive.metastore.uri=thrift://192.168.49.13:9083
The presto service run but it can not connect to hive because I use hadoop3 and when I change hive.properties,presto service can not run.
how can I connect to hadoop3?
Update:
it wasn't about hadoop. hive metastore was not installed correctly so presto had problem to connect hive metastore
we have hadoop cluster that contain all the relevant components/services as
HDFS
YARN
mapreduce
HIVE
Tez
pig
Zookeeper
hadoop clutser contain 3 masters machines and 12 data node machines and 3 kafka
now we want to use presto to run query against data sources ( hadoop cluster / hive )
so we build a new presto cluster as the follwing
1 presto coordinator
8 presto workers
all presto cluster machines are redhat 7.2
now we want to install the presto on all OS
but we are not sure if presto can be installed immodestly after Linux scratch OS
or maybe we need to install something in the middle after the OS and before the presto ?
The only requirement for Presto is a Java Virtual Machine (JVM). We recommend installing the latest OpenJDK 11 version, currently 11.0.2. After that, follow the Presto deployment instructions.
Python is required for the launcher (the script that starts the JVM), but this is normally available on a typical Linux distribution.

I am having 1 hiveserver2 in 30 node cluster now I wan to make 4 hiveserver2 daemon through ambari. How can i make multiple hiveserver2 in HDP 2.2 and ambari 1.7 ?
I know we can start hive server directly and set the properties to auto search but this daemon we cant monitor through ambari.
It's only supported in Ambari 2.0.0: https://issues.apache.org/jira/browse/AMBARI-8906
