How to get all the metrics via Metrics Servlet in JSON format (as in Web UI) from Apache Spark -


the apache spark web ui gives ton of useful information workers, driver, storage etc. metrics servlet gives few information. eg, following /metrics/json :

{   "version":"3.0.0",   "gauges":{     "local-1431683138663.<driver>.blockmanager.disk.diskspaceused_mb":{       "value":0     },     "local-1431683138663.<driver>.blockmanager.memory.maxmem_mb":{       "value":3179     },     "local-1431683138663.<driver>.blockmanager.memory.memused_mb":{       "value":169     },     "local-1431683138663.<driver>.blockmanager.memory.remainingmem_mb":{       "value":3009     },     "local-1431683138663.<driver>.dagscheduler.job.activejobs":{       "value":1     },     "local-1431683138663.<driver>.dagscheduler.job.alljobs":{       "value":1     },     "local-1431683138663.<driver>.dagscheduler.stage.failedstages":{       "value":0     },     "local-1431683138663.<driver>.dagscheduler.stage.runningstages":{       "value":1     },     "local-1431683138663.<driver>.dagscheduler.stage.waitingstages":{       "value":0     }   },   "counters":{   },   "histograms":{   },   "meters":{   },   "timers":{   } }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
