> Key: AMBARI-10837
> URL: https://issues.apache.org/jira/browse/AMBARI-10837
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.1.0
> Reporter: Myroslav Papirkovskyy
> Assignee: Myroslav Papirkovskyy
> Priority: Critical
> Fix For: 2.1.0
>
>
> HDFS configs review was done and the configs spreadsheet has been updated
> with various changes where the following must be fixed.
> * Below configs are to be marked as {{depends_on}} {{namenode_heapsize}}, and
> their value should be derived from it (basically ignore document value for
> below configs). Whenever {{namenode_heapsize}} changes in UI, below config
> values should also be updated
> ** namenode_opt_newsize (hadoop-env.sh) = {{namenode_heapsize/8}}
> ** namenode_opt_maxnewsize (hadoop-env.sh) = {{namenode_heapsize/8}}
> * {{dfs.namenode.safemode.threshold-pct}}
> ** minimum = 0.990f
> ** maximum = 1.000f
> ** default = 0.999f
> ** increment-step = 0.001f
> * {{dfs.datanode.failed.volumes.tolerated}} should be {{depends_on}}
> {{dfs.datanode.data.dir}}. So if a user adds additional folder in
> {{dfs.datanode.data.dir}}, then the *value and maximum* of
> {{dfs.datanode.failed.volumes.tolerated}} should change accordingly.
> * {{namenode_heapsize}} calculations should take into account host memory
> limits. Namenode_heapsize should be the {{host-memory -
> os-reserverd-memory}}. Also, if there are any other master-components on the
> same host, then it should be halved (namenode_heapsize/2).
