This role's Heap Dump Directory is on a filesystem with less than 10.0 GiB of its space free. /tmp

New Contributor

I am Getting the following warning on my cluster:

This role's Heap Dump Directory is on a filesystem with less than 10.0 GiB of its space free. /tmp

 

the following is df -h command on the partition

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/rhel-root 40G 32G 5.8G 85% /

 

how to resolve this issue as i cant find any log or temp files on this filesystem.

also there most of it is being consumed by this folder

21G /var/lib/solr-infra/ranger_audits_shard1_replica_n1/data

 

Any suggestions.

Hello @OmarElSeihy 

 

Thanks for using Cloudera Community. Based on the Post, your Team is receiving a Warning [1].

  • By default, the Role uses "/tmp" for -XX:HeapDumpPath. Your Team need to change the Value set for -XX:HeapDumpPath to a Mount, wherein your Team have Sufficient Space.
  • Alternatively, Your Team can work on reducing the FileSystem Usage on the concerned Mount Point. 
  • This Warning is an Alert for Cluster Admin & has no impact on any Service Usage in the Cluster. 
  • Sharing a Screenshot showing the Config Changes required, if your Team wish to modify the HeapDump Path & the Warning Threshold (Example shown for Solr Service as used Solr in the Post Tags):

@OmarElSeihy ,

 

Note that the error message says that the filesystem that's low on space is /tmp. The df result that you listed in your post is for the root filesystem (/).

Please run a "df -h /tmp" and check that filesystem for content that could be cleaned.

 

Cheers,

André
