Hello,

We are using Cloudera Manager 5.7.0 with cloudera parcels 5.7.0. We have found that some files in /run/cloudera-scm-agent/process/* are filling up disk space. Here's some examples :

[root@cdh02:/run/cloudera-scm-agent/process]# ls -larth | grep collect-host-statistics

Is there a Cloudera manager configuration to manage this ? My colleague found that it seems to rotate the file every 7 days (like defined in one of the retention policy). But shouldn't it clean the old files afterwards ?

Is this the normal behavior ? Are these files still useful ? Can we delete them safely ?
