Subject [jira] [Commented] (ATLAS-409) Atlas will not import avro tables with schema read from a file
Date Tue, 22 Dec 2015 21:24:46 GMT

    [ https://issues.apache.org/jira/browse/ATLAS-409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15068752#comment-15068752

Aaron Dossett commented on ATLAS-409:
-------------------------------------

[~yhemanth] [~shwethags]

To recreate this error 
- copy "foo.avsc" to HDFS
- run "example.ddl" with the appropriate HDFS path to foo.avsc
- run the hive bridge

[~yhemanth] Thank you for the test example! I will try to include that as well, assuming this
patch is otherwise agreed to.

> Atlas won't import a Hive table with no columns (see below for an example of a valid
hive table with no explicit columns).  This is because the Atlas Hive Storage Descriptor class
REQUIRES columns, but the Hive Table class allows them to be OPTIONAL.

>   ROW FORMAT SERDE
>   'org.apache.hadoop.hive.serde2.avro.AvroSerDe'
>   STORED AS INPUTFORMAT
>   'org.apache.hadoop.hive.ql.io.avro.AvroContainerInputFormat'

>   TBLPROPERTIES (
>     'avro.schema.url'='file:///path/to/the/schema/test_serializer.avsc');
> {code}
