[CARBONDATA-2043] Configurable wait time for requesting executors andâ¦
**Problem**
In case of spark.dynamicAllocation.enabled to true, during the block
distribution based on the needs of required number of executors carbon request
the executors from sparks and waits for specified time
for required executor's to come up before starting the block distribution.
Carbon waits for the specified time even if not possible to get the
required number of executors.
**Solution**
Configurable wait time for requesting executors and minimum registered
executors ratio to continue the block distribution
- carbon.dynamicAllocation.schedulerTimeout : to configure wait time.
defalt 5sec, Min 5 sec and max 15 sec.
- carbon.scheduler.minRegisteredResourcesRatio : min 0.1, max 1.0 and
default to 0.8 to configure minimum registered executors ratio.
