Hi Sridhar Reddy, How are you doing ? Thank you for your detailed explanation on automating the Ambari LDAP sync process. I tried to use the curl command you provided above by tweaking little bit and tested. I am running into issues and the logs doesn't have enough info. Below is the command I am using curl -v -k -u userid -H 'X-Requested-By: ambari' -X POST -d '[{"Event": {"specs": [{"principal_type":"groups","sync_type":"specific",
"names": "i listed the AD groups we have"}]}}]' http://ambarihostname:8080/api/v1/ldap_sync_events I get a result like this Enter host password for user 'userid':
* About to connect() to ambarihost port 8080 (#0)
* Trying IP address...
* Connected to ambarihost (IP address) port 8080 (#0)

Hi @Jay Kumar SenSharma - Increasing the timeout parameters helped to a certain extent but it didn't totally resolve the issue. The issue is occurring even after increasing the timeouts. Are there any other parameters that can be tweaked ? We are currently on Ambari Version 2.5.0.3 Thanks!

@Aravindan Vijayan - We have a 20 node Hadoop cluster. We installed the Base service completely in our cluster. The Ambari metrics collector mode - embedded. We are noticing the Ambari metrics collector starts and stops soon after some time. Checking the logs below is the error 2017-12-12 11:03:38,443 ERROR org.apache.hadoop.hbase.zookeeper.ZooKeeperWatcher: hconnection-0x70cf32e3-0x1604b8318690004, quorum=hdpmprod000.corp.pgcore.com:61181, baseZNode=/ams-hbase-unsecure Received unexpected KeeperException, re-throwing exception org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /ams-hbase-unsecure/meta-region-server Since we do not have HBase service in our cluster - Can I comment out all the AMS - HBase configuration to avoid the AMS-Hbase related issues or what is the best way to handle it. Any help is much appreciated. Thanks, Abhishek

Hi Geoffrey, Let me give you a little overview on how and where it all started. Since we have only one Hadoop Cluster which started as a POC and later it was converted to Production environment , we didn't have a lower environment similar to production for testing. So I planned to standup a production like environment with 10 nodes. I requested for 10 new virtual machines with RHEL 6.9 from devops team at our organization. They provided me 10 new vm's.Brand new vm's with no applications running on it. The devops team did one additional step on the new vm's - enabled chef on the new vm's. Upon the chef-client run it downloaded the below HDP repos , I didn't download the HDP repos neither I used them. I only downloaded ambari repo using the below links repo id repo name
HDP HDP Version - HDP-2.3.4.0
HDP-UTILS HDP Utils Version - HDP-UTILS-1.1.0.20 Ambari-2.5.0.3 Repo Download Link
wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.5.0.3/ambari.repo -O /etc/yum.repos.d/ambari.repo I can stop the chef-client on the new vm's and remove the HDP repos. I want to setup a cluster with Ambari - 2.5.0.3 in the lab environment because currently we are running Ambari - 2.5.0.3 in production. We are planning to upgrade the Ambari version in production. Since I don't have a environment to test the upgrade , I wanted to setup the lab environment with the similar Ambari version in production and ran into ambari-setup issues. The VM's doesn't have any HDP packages installed or distributed. The VM's are all new and having nothing related to HDP. Please let me know if you need any further information or a webx session to look into it further. Thanks

Hi Geoffrey, Thank you very much for taking time and testing the installation. I have gone through all of your screenshots. This is what I am planning to do but I am running into issues at the very beginning of the installation of Ambari Server. I will further research into the issue I am running into. Will update you if I find anything. Thank you very much for your time and fast response. Have a great weekend! Thanks
