It is used to read thrift data files. AFAIK no one uses thrift for data 
serialization.

 Summary: Avoid sending configs to tasks and AM which are only

  Issue Type: Task

There are many configs which are only relevant for HS2. Longer term fix for 
this is to split HiveConf in multiple config classes relevant only for HS2, 
HMS, AM and tasks. And use only the objects in process where its relevant. In 
the interim, we can avoid configs with large value strings to send across.

These configs were introduced in HIVE-3708 in the hope to develop tools to 
visualize and monitor multiple MR jobs from Hive back in a day when MR was 
used. Even that time in spite of these config additions, no such tools were 
developed AFAIK. And now MR is hardly ever used. We can get rid of these 
configs. That will help to reduce the size of HiveConf by a bit.

Activemq is a test dependency introduced to test message bus feature in

activemq as a dependency. 
https://issues.apache.org/jira/browse/HCATALOG-3?focusedCommentId=13035113=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-13035113
AFAIK no one uses message bus feature of HCatalog. We can remove it altogether. 
As a first step removing tests for it.

Default value is 0.5 Lets update it to 0.99
In average case its a trade-off between cpu vs network. Erring on side of CPU 
is better since perf loss caused by network is usually larger.

Reporter: Ashutosh Chauhan


HIVE-17465 introduced progressive scaling of rowcounts in presence of multiple 
filters. HIVE-19500 improved on that by also scaling col stats (NDV) in such 
scenario. However, it should pay attention to column used in filter expression 
and not scale for all filters. eg.,
consider filter a = 1 and b = 2 ndv of column b should not be scaled down by 
row count changes caused by a = 1
Other way to say this that ndv of a particular column should be updated at the 
end of computation of row count for that operator.

Following works:

insert into t1 values (1,2,3);

insert into t1 (c, b, a) values (1,2,3);

insert into t1 (a,b) values (1,2);

{code}

For partitioned tables it should work similarly but doesn't.  All of following 
fails:

{code}

insert into t2 values (1,2,3,4);

insert into t2 (a, b, c, d) values (1,2,3,4);

insert into t2 (c,d) values (1,2);

insert into t2 (a,b) values (1,2);

Most common way to implement this is via ordered aggregate which allows users 
to specify sort specification with group by clause. Some implementations also 
allow to use these with window functions.

Since Hive doesn't have concept of ordered aggregates yet, one possibility is 
to support these only for window functions where sort specification is also 
taken from window clause.
