During the initial setup of HDFS using Ambari, configuring the pathway to /home/hadoop/hdfs/data, or any /home pathway for that matter, is illegal. After further digging and research, it is written as a security measure to prevent writing to the /home directory. I had to literally take the long way home. ... View more

@slachterman while this didn't directly help me solve the problem, it did help me think of a way to come to the solution. Thank you for the help! ... View more

@slachterman, each VM has the OS (CentOS7) running on their respective hdd and partitioned accordingly. The DN directory is pointing to /hadoop/hdfs/data. However, according to the partition sizes of the OS, this folder is limited to 50 gb. The rest is dedicated to the /home partition, just over 1.7tb on each DN. I did notice during the install of Ambari I was not allowed to point my NameNode or DataNode to /home. Is this the problem? ... View more

@slachterman Thank you for responding. The CRIT alert is stating my NameNode capacity is maxed out and the dfsadmin report on the NameNode is stating the same: all 28kb of the dfs are used. As I run the same report on the DataNodes, I get the same results, they only have 28kb allocated to dfs and they are full as well. As for the setup, I am using 1x physical machine with 1TB hdd to run the Ambari server/Edge Server/Secondary Master, 1x VM w/ 1TB hdd to run as Primary Master, and 3x VMs (each with a dedicated 2TB hdd) to run as the DataNodes. The purpose of this cluster is to act as a DEV/Admin Sandbox until I am given the funds to build a proper cluster. On a side note, is there much difference in setting up a cluster with physical machines vs VMs? I wouldn't think so as they both require separated networks and similar design and deployments. Then again, nothing about this setup has gone right so far... ... View more

This is what I was expecting, but this is what I am given to work with, sadly. Thank you for your input. I am hoping if this build goes well, then I can convence the "powers at be" for a bigger budget to build a proper cluster. Thank you again. ... View more

I am using 2.5 and still getting the same error when I try to delete the auto generated Hive View Instance. Does this patch work? How do I patch Ambari? Is there a way to manually remove the instance outside of Ambari (ie through the terminal)? Thank you in advance. ... View more

Thank you for your response. I have the other three already mounted to the base system (/mnt/...), named Data1, Data2, Data3 already. How do I mount them to hadoop? Is this a configuration in Ambari/HDFS? Or is this something I must do in terminal? Again, still learning the finer details of this system. Thanks. ... View more
