Subject [jira] [Commented] (HIVE-9274) STORED BY not setting input and output formats correctly
Date Thu, 08 Jan 2015 21:52:35 GMT

    [ https://issues.apache.org/jira/browse/HIVE-9274?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14270096#comment-14270096
] 

Thomas Friedrich commented on HIVE-9274:
----------------------------------------

Looks like this behavior has changed due to HIVE-6584. In DDLTask the input and output format
classes are only persisted when explicitly specified. I wonder if the documentation in https://cwiki.apache.org/confluence/display/Hive/StorageHandlers
should be updated (under open issues: "Names of helper classes such as input format and output
format are saved into the metastore based on what the storage handler returns during CREATE
TABLE; it would be better to leave these null in case they are changed later as part of a
handler upgrade").

>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: 0.14.0
>            Reporter: Thomas Friedrich
>            Priority: Minor
>
> When creating a new table using a storage handler via the STORED BY clause, for example
using the HBaseStorageHandler, the input and output formats are set to null instead of the
correct formats:
> CREATE TABLE hbase_table_1(key int, value string) 
> STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
> WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf1:val")
> TBLPROPERTIES ("hbase.table.name" = "xyz");
> describe formatted hbase_table_1:
> # Storage Information
> SerDe Library:          org.apache.hadoop.hive.hbase.HBaseSerDe
> InputFormat:            null
> OutputFormat:           null
> In older Hive versions, it would set the correct formats.
> Could it be related to the changes in HIVE-5976?
