Map 1 <- Map 4 (BROADCAST_EDGE)
Reducer 2 <- Map 1 (CUSTOM_SIMPLE_EDGE), Map 5 (CUSTOM_SIMPLE_EDGE)
Reducer 3 <- Reducer 2 (SIMPLE_EDGE)
set hive.tez.max.partition.factor=0.5f;
This causes "Reducer 3" to have 0 tasks, causing the job to fail after reducer
2.
Will attach the plan and screenshot shortly
