Hi All, I recently upgraded from 1.10.0 to 1.12.0 and in my one of query I got below error :- INFO o.a.d.e.p.i.aggregate.HashAggregator - User Error Occurred: Not enough memory for internal partitioning and fallback mechanism for HashAgg to use unbounded memory is disabled. Either enable fallback config drill.exec.hashagg.fallback.enabled using Alter session/system command or increase memory limit for Drillbit org.apache.drill.common.exceptions.UserException: RESOURCE ERROR: Not enough memory for internal partitioning and fallback mechanism for HashAgg to use unbounded memory is disabled. Either enable fallback config drill.exec.hashagg.fallback.enabled using Alter session/system command or increase memory limit for Drillbit
Can anybody tell me working of "drill.exec.hashagg.fallback.enabled" variable. Should we always set it to true as it is false by default? Regards, Anup Tiwari
