INSERT failed in Hive on tez but queries function...

Hello,      I was running an INSERT in Hive on tez. It failed with the following error messages:   Query ID = atguigu_20220309164809_a7f22472-57c1-456d-bfa4-b114f4170db1 Total jobs = 1 Launching Job 1 out of 1 FAILED: Execution Error, return code -101 from org.apache.hadoop.hive.ql.exec.tez.TezTask. org.apache.hadoop.security.UserGroupInformation.getGroups()Ljava/util/List;        Then I changed by setting  hive.execution.engine=mr and re-ran my INSERT.  It failed again with the following new messages:   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 mapreduce.job.reduces=<number> java.io.IOException: Unable to close file because the last block does not have enough number of replicas.         To save disk space, I set replica to 1 in hadoop.  What's strange is all queries work well in the same environment.
