> Adjust new KuduStorageHandler package
> -------------------------------------
>
> Key: IMPALA-8629
> URL: https://issues.apache.org/jira/browse/IMPALA-8629
> Project: IMPALA
> Issue Type: Sub-task
> Components: Catalog, Frontend
> Reporter: Grant Henke
> Priority: Major
>
> Before releasing with the updated KuduStorageHandler, we should change the new KuduStorageHandler package from “org.apache.kudu.hive” to “org.apache.hadoop.hive.kudu”.
>
> This should being done to ensure the stand-in storage handler can be a real storage handler when a Hive integration is added in the future. The “org.apache.hadoop.hive” package is the standard package all Hive storage handlers lives under.
>
> Additionally the stand-in format details defined [here|https://github.com/apache/impala/blob/2bce974990e19788ec359deec50f06d44ec92048/fe/src/main/java/org/apache/impala/catalog/HdfsFileFormat.java#L70] should be updated as well. Values for those entries should be:
> {noformat}
> org.apache.hadoop.hive.kudu.KuduInputFormat org.apache.hadoop.hive.kudu.KuduOutputFormat org.apache.hadoop.hive.kudu.KuduSerDe
> {noformat}
>
> I have a WIP patch for HIVE-12971 and used that patch to validate that using "correct" stand-in values would allow Hive to read HMS tables/entries created by Impala.
>
> Note: This patch will need to be committed after the Kudu side patch is committed and the Kudu build/version may need to be update in Impala. A review for the Kudu side change is here: [https://gerrit.cloudera.org/#/c/13540/]
