Dear all,

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

disable IPv6

Add the following to /etc/sysconfig/network:

NETWORKING_IPV6=no

IPV6INIT=no

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

set ulimits

$ 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.

Note: No parcels found from the configured repositories. Try adding a Custom Repository under More Options. Otherwise, you may only proceed with Use Packages.

2. At step 5

Cluster Installation

Detecting CDH versions on all hosts

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?

anyone can help me?

This link has the parcels present in it. http://archive.cloudera.com/cdh5/parcels/

You can enter this link in the parcel location, distribute your parcels and then you will be able to go further.

tuongnguyen · ‎03-24-2017

It's defaut link. and it always appears.

I think problem is proxy, after setup proxy, we must wait?

tuongnguyen · ‎03-24-2017

After parcel downloaded. It did not run any more ?

tuongnguyen · ‎03-26-2017

surajacharya · ‎03-28-2017

After it is downloaded, you will need to distribute it and unpack it too.

email2dgk · ‎03-28-2017

@surajacharya

What if the screen freezes and no progress though the Download shows 100% but distribute 0/4 , Unpack 0/4 and Activate 0/4?

adminzeeshan · ‎03-28-2017

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

http://www.ubuntumag.com/install-java-8-jdk-8u31-on-centos-rhel-765-fedora/

4. Start the server and the agent .

feel free to contact me for any further support on this freeze distribution issue CDH 5.10

email2dgk · ‎03-28-2017

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
java-1.8.0-openjdk-headless-1.8.0.121-0.b13.el7_3.x86_64
java-1.8.0-openjdk-1.8.0.121-0.b13.el7_3.x86_64
jdk-1.6.0_31-fcs.x86_64
copy-jdk-configs-1.2-1.el7.noarch

[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
/usr/java/jdk1.8.0_121
[root@namenode1 ~]#

Let me try to remove openJDk

adminzeeshan · ‎03-28-2017

u have installed open jdk again it is supporting orcale jdk in my case find the installation instructions below .

http://www.ubuntumag.com/install-java-8-jdk-8u31-on-centos-rhel-765-fedora/

remove open jdk by

$ yum remove java-o*

or

$ yum remove javao*

This will be fixed in the next maintenance release 5.10.1, 5.9.2.

adminzeeshan · ‎03-28-2017

any idea when this release will be offically available

Shrilesh · ‎05-31-2017

Hi,

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

adminzeeshan · ‎05-31-2017

Yes open jdk is conflicting with it . just remove them

Shrilesh · ‎06-09-2017

Thanks alot @adminzeeshan, yes it was due to open JDK.

Issue is resolved and installation is successful.

Regards,

Shrilesh
