org.apache.tez.dag.api.TezUncheckedException: Invalid max/min group lengths.
Required min>0, max>=min. max: 4194304 min: 16777216 Cause:- In the client app ( Jmeter ) we are setting 3
parameters as below:- set mapreduce.job.maps=64; set tez.grouping.max-size=4194304; set tez.grouping.min-size=2097152; In Tez configuration ,
the max size is set as 1GB and min size as 16777216. Now if you see the error ,
max shown as 4194304 which is that we exactly set through Jmeter and min
is 16777216 which is the tez default parameter. So that means hive is
taking the max from jmeter and min from tez default configuration and this is
the cause of the issue.
