[jira] [Created] (AMBARI-10602) HDFS namenode_opt_newsize and
namenode_opt_maxnewsize not using number of datanodes in calculation
Dmytro Sen created AMBARI-10602:
-----------------------------------
Summary: HDFS namenode_opt_newsize and namenode_opt_maxnewsize not using number of datanodes in calculation
Key: AMBARI-10602
URL: https://issues.apache.org/jira/browse/AMBARI-10602
Project: Ambari
Issue Type: Bug
Components: stacks
Affects Versions: 2.1.0
Reporter: Dmytro Sen
Assignee: Dmytro Sen
Fix For: 2.1.0
Reviewing HDFS recommendation code for namenode_heapsize, namenode_opt_newsize and namenode_opt_maxnewsize, it looks like the calculations are not taking into account the number of datanodes and disks per datanode.
HDFS recommendations currently gives the following output
{code}
"configurations": {
"hadoop-env": {
"properties": {
"namenode_heapsize": "1024",
"namenode_opt_maxnewsize": "256",
"namenode_opt_newsize": "256"
},
"property_attributes": {
"namenode_heapsize": {
"maximum": "2887"
},
"dtnode_heapsize": {
"maximum": "2887"
}
}
},
{code}
