---------------------------------------------------------------
We hit this problem as well (at least on sqoop 1.4.6, parquet backed Hive
table).
Not sure if related to
[SQOOP-2858|https://issues.apache.org/jira/browse/SQOOP-2858], as that problem
seems specific to avro. Definitely the same as
[SQOOP-1538|https://issues.apache.org/jira/browse/SQOOP-1538] though.

> Using hcatalog with --update-key does not work

> Key: SQOOP-2948
> URL: https://issues.apache.org/jira/browse/SQOOP-2948
> Project: Sqoop
> Issue Type: Bug
> Reporter: Charles Yeh
> Priority: Major
>
> When trying to export Hive to MySQL with Sqoop, I found that using hcatalog
> with --update-key would error.
> This command worked:
> env HCAT_HOME=/srv/hive-latest/hcatalog HADOOP_USER_NAME=hadoop sqoop export
> -Dquery_source=sql_export -Dhive.metastore.uris=thrift://<DELETED>:9083
> -Dmapred.job.queue.name=ETL-nonSLA -Dmapred.job.name=attempt --hive-home
> /srv/hive-latest --hcatalog-database charlesyeh --connect
> 'jdbc:mysql://10.16.101.24/sql_export?user=<DELETED>&password=<DELETED>&charset=utf8&connect_timeout=3&use_unicode=1'
> --hcatalog-table result7660208 --table test_ss
> Adding only "--update-key id" at the end of the previous command made it
> fail. The output was:
> ...
