Concatenating ORC files

Hi,
I'm trying to use the new concatenate command merge small ORC files and
file right away:

 alter table requests partition(day_ts=1418083200, hour_ts=1418151600)
concatenate;

Diagnostic Messages for this Task:

Is there some property I need to set for ORC to be able to support
concatenation?

Thanks,
Daniel

HI Prasanth,
The first attempt had ("orc.compress"="Snappy") and all the files under it
were created the same way so I'm assuming they all should have indexes
created.
In the second attempt I used ("orc.create.index"="false",
"orc.compress"="Snappy").

Thanks,
Daniel

Re: Concatenating ORC files

Hi Daniel




In you first run, are there some files with “orc.create.index”=“false”? What are the table properties used to create ORC files in both cases?

Re: Concatenating ORC files

Posted by Prasanth Jayachandran <pj...@hortonworks.com>.
I am unable to reproduce the case that causes exception that you are seeing. Will be great if you can provide a repro.

Re: Concatenating ORC files

Posted by Prasanth Jayachandran <pj...@hortonworks.com>.
I can see a bug for the case 2 where orc index is disabled. I have created a jira to track that issue.

https://issues.apache.org/jira/browse/HIVE-9067





I am not sure why does it fail in case 1 though. Can you create a jira with a reproducible case? I can take a look at it.

Re: Concatenating ORC files

I've made a little experiment and recreated the table
with 'orc.create.index'='FALSE' and now it fails on something else:
Error: java.io.IOException:

It seems that the concatenation feature needs more work..
