apache - Does cloudera distribution of hadoop use the control scripts? -


are control scripts (start-dfs.sh , start-mapred.sh) used cdh start daemons on distributed cluster? downloaded , installed cdh5, not see control scripts in installation, , wondering how cdh start daemons on slave nodes?

or since daemons installed services, start system start-up. hence there no need control scripts in cdh unlike apache hadoop.

not such, no. if recall correctly, cloudera manager invokes daemons using supervisor (http://supervisord.org/). so, manage services in cm. cm runs agent processes service on each node, , can find start script in /etc/init.d. there no need install or start or stop anything. install, deploy config, control , monitor servies in cm.

i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
