Hello,
i installed HUE4.2 version compiling the code from git. It works all fine, but when i try to load the data from the old HUE (3.9.0) i get an error regarding a non existing field
Before upgrading i did the following steps
1-Stop HUE
2- backup the db (hue/build/env/bin/hue dumpdata > ./hue-mysql.json)
3- dropped the database
4- Created a new empty database
CREATE DATABASE huedb DEFAULT CHARACTER SET utf8 DEFAULT COLLATE=utf8_bin;
5- Synchronized the new dabase
hue/build/env/bin/hue syncdb --noinput
hue/build/env/bin/hue migrate
6- And loaded the data previously backup
hue/build/env/bin/hue loaddata ./hue-mysql.json
I get this error
File "/app/hue/build/env/lib/python2.7/site-packages/Django-1.11-py2.7.egg/django/db/models/options.py", line 619, in get_field
raise FieldDoesNotExist("%s has no field named '%s'" % (self.object_name, field_name))
django.core.serializers.base.DeserializationError: Problem installing fixture '/app/temp/hue-dump.json': ContentType has no field named 'name'
I compared the tables from the 3.9 and 4.2 versions and i see a difference in the fields
mysql> describe django_content_type;
3.9
+-----------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------+--------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| name | varchar(100) | NO | | NULL | |
| app_label | varchar(100) | NO | MUL | NULL | |
| model | varchar(100) | NO | | NULL | |
+-----------+--------------+------+-----+---------+----------------+
4.2.0
mysql> describe django_content_type;
+-----------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------+--------------+------+-----+---------+----------------+

| app_label | varchar(100) | NO | MUL | NULL | |
| model | varchar(100) | NO | | NULL | |
+-----------+--------------+------+-----+---------+----------------+
The name field is not present anymore.
Is there any extra step that i should considered when migrating the database:
I'm using a mySQL standalone DB (not using CDH)
Thank you
Paula
