Attachment: HIVE-19157.2.patch
> Assert that Insert into Druid Table fails if the publishing of metadata by
> HS2 fails
> ------------------------------------------------------------------------------------
>
> Key: HIVE-19157
> URL: https://issues.apache.org/jira/browse/HIVE-19157
> Project: Hive
> Issue Type: Bug
> Reporter: slim bouguerra
> Assignee: slim bouguerra
> Priority: Major
> Attachments: HIVE-19157.2.patch, HIVE-19157.patch
>
>
> The usual work flow of loading Data into Druid relies on the fact that HS2 is
> able to load Segments metadata from HDFS that are produced by LLAP/TEZ works.
> In some cases where HS2 is not able to perform `ls` on the HDFS path the
> insert into query will return success and will not insert any data.
> This bug was introduced at function {code}
> org.apache.hadoop.hive.druid.DruidStorageHandlerUtils#getCreatedSegments{code}
>
> when we added feature to allow create empty tables.
> {code}
> try {
> fss = fs.listStatus(taskDir);
> } catch (FileNotFoundException e) {
> // This is a CREATE TABLE statement or query executed for CTAS/INSERT
> // did not produce any result. We do not need to do anything, this is
> // expected behavior.
> return publishedSegmentsBuilder.build();
> }
> {code}
> Am still looking for the way to fix this, [~jcamachorodriguez]/[~ashutoshc]
> any idea what is the best way to detect that it is an empty create table
> statement?
