please help me solve this problem:
When i tried to install cloudera manager (Path A) on Centos 7.3, I faced to alot of issue. Bellow, I will describe all step I did. Please tell me the wrong step if I have.
1. Install centos 7.3 on a computer with core i7 6700, ram 16gb, and hdd 2tb
2. Change hostname to cloudera1.abc.com.vn
3. change hosts file with information : 192.168.0.1 cloudera-1.abc.com.vn cloudera-1
4. In /etc/sysconfig/network file fill host name : cloudera-1
4. disable SELinux: SELINUX=disabled ( when i choise permissive, Cloudera alway alert Disable SELinux before install)
5. Setup proxy for yum.config
6. Some additional step
Add the following to /etc/sysconfig/network:
disable firewall, do the following
systemctl status firewalld.service
systemctl stop firewalld.service
systemctl disable firewalld.service
some performance setting
echo "vm.swappiness = 1" >> /etc/sysctl.conf
echo 1 > /proc/sys/vm/swappiness
$ echo hdfs - nofile 32768 >> /etc/security/limits.conf
$ echo mapred - nofile 32768 >> /etc/security/limits.conf
$ echo hbase - nofile 32768 >> /etc/security/limits.conf
$ echo hdfs - nproc 32768 >> /etc/security/limits.conf
$ echo mapred - nproc 32768 >> /etc/security/limits.conf
$ echo hbase - nproc 32768 >> /etc/security/limits.conf
Disable transparent huge page
echo never > /sys/kernel/mm/transparent_hugepage/defrag
echo never > /sys/kernel/mm/transparent_hugepage/enabled
It all thing I did before setup. Now I will tried to setup with the cloudera guideline, and go to link http://your.server.com:7180
1. At page Parcel, => No Parcels found. I must choise a pack
Versions of CDH that are too new for this version of Cloudera Manager (5.10.0) will not be shown.
2. At step 5
No CDH version detected. Check Again
Ensure that all hosts have the same CDH version and then click Check Again to proceed.
No CDH version detected. Check AgainEnsure that all hosts have the same CDH version and then click Check Again to proceed.
What should I do now?
After parcel downloaded. It did not run any more ?

Do you have any suggestion

for heart beat issue remove guid file from client it will work fine .
/var/lib/cloudera-scm-agent/cm_guid on each node
i tried it atleast 15-20 time from stratch and then found its an openjdk issue that was root cause of this issue remove
1. yum remove javaopen*
2. Stop the server and the agent
3.download and install the correct version JDK1.8_31
for your convinience find the link below
4. Start the server and the agent .
feel free to contact me for any further support on this freeze distribution issue CDH 5.10
At this moment, I have skipped the Cloudera Manager JDK installation since I have downloaded and installed JDK 1.8 on all the hosts and set the $JAVA_HOME as well. But still java -version points to open JDK.
[root@namenode1 ~]# rpm -aq | grep -i jdk
[root@namenode1 ~]# java -version
openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
[root@namenode1 ~]# echo $JAVA_HOME
Let me try to remove openJDk
u have installed open jdk again it is supporting orcale jdk in my case find the installation instructions below .
remove open jdk by
$ yum remove java-o*
$ yum remove javao*
Is this issue resolved ? were you able to bypass that "no cdh version detected" issue ?
I am facing this issue and have tried reinstall multiple times. But it gets stuck at same point every time
