Subject [jira] [Created] (SQOOP-2161) Incremental append on to Hive Parquet tables doesn't work

----------------------------------

             Summary: Incremental append on to Hive Parquet tables doesn't work
                 Key: SQOOP-2161
                 URL: https://issues.apache.org/jira/browse/SQOOP-2161
             Project: Sqoop
          Issue Type: Bug
          Components: hive-integration
    Affects Versions: 1.4.5
            Reporter: Mark Grover


I have some code that does incremental append to a Hive parquet table. I am able to get the
first time automatic table creation in Hive to work, but subsequent appends return errors.
Also, ideally, I would like to create the Hive table explicitly myself and only just do appends
to it.

More concretely, the code I am using is at https://gist.github.com/markgrover/86f54663ece0943bc8ed

I am also attaching two verbose error logs. Each of them contain, at the top, the command
ran.

new_pre_created_verbose.log contains the error which occurs if I try to import data into an
empty Hive parquet table that have been created in Hive. I ran the create table statement
in the above gist and it matches the source schema one-to-one.

In order to get past the above error, I don't run the hive create table command explicitly.
Sqoop then successfully creates the table and adds data to it. However, on the next run when
I want to append more data, I get another error which is detailed in append_pre_created_verbose.log
