----------------------------------
Summary: 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
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:
