Hi ,
We have a scenario to update a table from different set of tables for which
we are using hive 0.14.Here are the steps that we are following
1.Parent table is ORC table with ACID property.
2.Delta table has updated records that need to be inserted to parent
table(Delta table is also an ORC with ACID property).
3.Insert into table parent select * from delta table.
Throws below error :
java.lang.NullPointerException
