Denes Bodo updated SQOOP-3438:
------------------------------
Issue Type: Improvement (was: Bug)
> Sqoop Import with create hcatalog table for ORC will not work with Hive3 as
> the table created would be a ACID table and transactional
> -------------------------------------------------------------------------------------------------------------------------------------
>
> Key: SQOOP-3438
> URL: https://issues.apache.org/jira/browse/SQOOP-3438
> Project: Sqoop
> Issue Type: Improvement
> Components: hive-integration
> Affects Versions: 1.4.7
> Reporter: Denes Bodo
> Assignee: Denes Bodo
> Priority: Critical
> Time Spent: 1h
> Remaining Estimate: 0h
>
> PROBLEM: Running a sqoop import command with the option
> --create-hcatalog-table will not work due to the following reasons
> When create-hcatalog-table is used it creates the table as a Managed ACID
> table.
> HCatalog does not support transactional or bucketing table
> So customer who need to create a ORC based table cannot use sqoop to create a
> ORC based table which means their existing code where if in case they use
> sqoop to create these tables would fail.
> The current workaround is a two step process
> 1. Create the ORC table in hive with the keyword external and set
> transactional to false
> 2. Then use the sqoop command to load the data into the orc table.
> The request is to add in an extra argument in the sqoop command line to
> specify that the table is external (example: --hcatalog-external-table )so we
> can use the option --hcatalog-storage-stanza "stored as orc tblproperties
> (\"transactional\"=\"false\")".
> ----
> Thank you [~mbalakrishnan] for your findings. This ticket is created based on
> your work.
