[jira] [Commented] (SQOOP-3147) Import data to Hive Table in S3 in Parquet format

["Alwin James (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SQOOP-3147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15977856#comment-15977856 ] 

Alwin James commented on SQOOP-3147:
------------------------------------

[~akamal] For the issue 'Another issue that I noticed is that Sqoop loads the Avro schema in TBLProperties under avro.schema.literal attribute and if the table has a lot of columns, the schema would be truncated and this would cause a weird exception like this one.'

What is the hive metastore backend used? 
It could well be the case were it is hitting limitation on the number of characters that can be stored in TBLPROPERTIES in hive metastore.
By default it is 4000, you can try increasing the value.
