Gwenael Le Barzic updated AMBARI-7194:
--------------------------------------
Description:
Hello !
There is a problem with Ganglia in Ambari 1.6.0 and an Hadoop cluster HDP
2.1.3.
I modified the parameter "Ganglia rrdcached base directory" in Ambari.
Even after a restart of this component in Ambari the RRD files of Ganglia are
still using the same old path for the RRD files.
When I looked in /etc/ganglia/hdp/gmetad.conf, the paragraph for this path is
still commented.
#-------------------------------------------------------------------------------
# Where gmetad stores its round-robin databases
# default: "/var/lib/ganglia/rrds"
# rrd_rootdir "/some/other/place"
##EDIT##
In fact, by modifying the rrdcached_base_fir in Ambari, it modified indeed the
command line of rrdcached :
/usr/bin/rrdcached -p /var/run/ganglia/hdp/rrdcached.pid -m 664 -l
unix:/var/run/ganglia/hdp/rrdcached.sock -m 777 -P FLUSH,STATS,HELP -l
unix:/var/run/ganglia/hdp/rrdcached.limited.sock -b /opt/hdp/ganglia/rrd
But the problem is that rrdcached doesn't write anything in the folder
specified after -b and I don't know if it is not because of the path being not
set in the gmetad.conf file.
Best regards.
