Re: Null pointer exception on running compaction against an MM table

[Vaibhav Gumashta]

The approach is similar, but it is not identical. Let me go over the query 
based compaction codepath to see if I spot this bug there.

Thanks,

Hi,

Thanks for the reply, have opened a JIRA (HIVE-21280) for the same and will 
upload a patch soon. But I further had doubts on the new query based compactor 
for full CRUD tables that has gone into master in HIVE-20699. Does major 
compaction work there using query based compactor similar to the one for MM 
table, because I expect the same problem to exist there as well?

Aditya

Subject: Null pointer exception on running compaction against an MM table

Error! Filename not specified.
Hi,

I was trying to run compaction on MM table but got a null pointer exception 
while getting HDFS session path. The error seemed to me that session state was 
not started for this queries. Am I missing something here? I do think session 
state needs to be started for each of the queries (insert into temp table etc) 
running for compaction (I'm also doubtful for statsupdater thread's queries) on 
HMS. Some details are as follows:

Env./Versions: Using Hive-3.1.1 (rel/release-3.1.1)

Steps to reproduce:
1) Using beeline with HS2 and HMS
2) create an MM table
3) Insert a few values in the table
4) alter table mm_table compact 'major' and wait;
Stack trace on HMS:

compactor.Worker: Caught exception while trying to compact 
id:8,dbname:default,tableName:acid_mm_orc,partName:null,state:^@,type:MAJOR,properties:null,runAs:null,tooManyAborts:false,highestWriteId:0.

Serialization of HiveRelNodes

[mark pasterkamp]

Dear all,

First of all, I am sorry if I sent this message twice, I received no 
confirmation of my previous email actually reaching the mailing list.

For my project I want to be able to access the HiveRelNodes for some extended 
semantic analysis. By extending the hookcontext and adding a new hook I have 
been able to access them serverside.

To gain access to them from a client perspective I was thinking about 
serializing them and then deserialize them from the client (perhaps by storing 
the serialized form in a table). Since the RelNode and HiveRelNode classes do 
not implement the Serializable interface I thought maybe I could use the 
RelJsonWriter and RelJsonReader instead. However the RelJsonWriter is not able 
to convert the HiveRelNodes into a json format.

Would anyone perhaps know of a different solution to serializing and 
deserializing these HiveRelNodes?


With kind regards,

Mark

It seems like more accurate equals/hashcode have caused this change; before 
CALCITE-2632 RexCorrelVariables were not properly compared; it seems like that 
have helped/interfered with HiveRelDecorrelator's operations.

https://github.com/apache/calcite/blob/ef9f926061de21ad713a76ec3ec8110e5cbd92bf/core/src/main/java/org/apache/calcite/rex/RexCorrelVariable.java#L59

the join order is essentially the same

* one of the higher level inner join have its arguments swapped in the output.
* the new plan has 1 projection happening earlier than in the old
* has 1 new projection

How to use Replace Columns function

[Yasunori Oto]

Hi all,



We have been developing the schema-less file format like JSONSerDe.

https://github.com/yahoojapan/yosegi



We implement its SerDe to access data by their column names.

Then, we want to define and change the table at any field names.



We found the Replace Columns function in Hive.

However, this operation allows the only predefined SerDes for listing in the 
code.

https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/DDLTask.java#L3960-L3968



So, could you please teach us how to use this kind of function?

Or discuss to open this function for other SerDe like us.



Yasunori
