directories.pngHi, I see that by default after the automated install using Ambari, there are bunch of directories under name node and data node settings in the configuration. Can you tell me if that is the best practice or if we should remove some directories in that and keep only one in each. Also please let me know if removing those do not affect the hdfs services. Thanks, Chandra

dont know what i did..but i tried restarting each service manually using command line and it started working. One wierd thing is that if i try to start all the services from the Ambari dashboard it does not work. But i try to start all the services from the hosts page which says "start all host components" it works. Also the zookeeper service keeps stopping all the time. otherthan that all the services are running fine. Any suggestions will be greatly appreciated.

Hi, We installed HDP using root account successfully and the services came up after the install ok with no issues. But now, all services are down and we see the message "Connection failed: [Errno 111] Connection refused to sibi1b.gov.calgary.ab.ca:" Not sure what is going on...Anyone had this issue and the resolution. Any help will be greatly appreciated. Rebooting the server didn't help as well. Thanks Chandra

Hi, Since the largest folder in HDP is under /usr/hdp, we are planning to mount it in advance as 50G prior to running the installation. Will it delete and recreate the folder while running the installation? This was the recommendation from unix team. Please let me know Thanks

Also can you tell me the location where it is installed. We have to allocate proper space to that specific location.
