-----------------------------------
Summary: Grouping should generate consistent groups when given the
same set of Splits
Key: TEZ-1396
URL: https://issues.apache.org/jira/browse/TEZ-1396
Project: Apache Tez
Issue Type: Improvement
Reporter: Siddharth Seth
Assignee: Siddharth Seth
Currently, it seems like Grouping can end up generating a different set of
groups on different invocations of the same set of splits and target tasks.
The order likely gets affected by the randomization in the block location
report from HDFS.
This should be consistent for better cache utilization.
