Input file does not exist (_SUCCESS)

I am hitting an error late using Hive to run a INSERT/SELECT query, which was running fine for the last few months.


I kept getting this type of error:


Launching Job 4 out of 7
Number of reduce tasks not specified. Estimated from input data size: 1
In order to change the average load for a reducer (in bytes):
set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:
set hive.exec.reducers.max=<number>
In order to set a constant number of reducers:
set mapred.reduce.tasks=<number>
org.apache.hadoop.mapred.InvalidInputException: Input path does not exist: hdfs://nameservice01/some_projectdirectory_D1/someTable_T1/_SUCCESS


Any idea what is the cause of this?
