Thanks @Kuldeep Kulkarni This has cleared some doubts about how Hadoop services auto-login even though initial user TGT shows expired.

You should look at the flink programming guide, it's pretty detailed and addresses many scenarios, your question is to general. https://ci.apache.org/projects/flink/flink-docs-master/apis/batch/index.html

closing the Question with the Kuldeep's suggested link https://hive.apache.org/javadocs/r0.10.0/api/org/apache/hadoop/hive/ql/ppd/PredicatePushDown.html

The command set hive.enforce.bucketing = true; allows the correct number of reducers and the cluster by column to be automatically selected based on the table. Otherwise, you would need to set the number of reducers to be the same as the number of buckets.

partition is two types, 1.static, 2.dynamic, splitting the data concept, see this blog for more good example to learn hive partition and bucketing

Yes ascending is usually a default in most languages. https://pig.apache.org/docs/r0.14.0/basic.html#order-by Usage Note: ORDER BY is NOT stable; if multiple records have the same ORDER BY key, the order in which these records are returned is not defined and is not guarantted to be the same from one run to the next.
