build/env/bin/hue migrate failed during upgrade.

[Anandha Loganathan]

I am upgrading hue to 4.1.0. During the process,  "migrate' is failing with OOM exception.   Increasing memory is a very cumbersome process and it has to go through the different process. Is there a way to fix the problem other than increasing memory?

FATAL ERROR - The following SQL query failed: ALTER TABLE `desktop_document2` ADD COLUMN `is_trashed` bool NULL;

The error was: (1041, "Out of memory; check if mysqld or some other process uses all available memory; if not, you may have to use 'ulimit' to allow mysqld to use more memory or you can add more swap space")

 ! Error found during real run of migration! Aborting.

 ! Since you have a database that does not support running

 ! schema-altering statements in transactions, we have had

 ! to leave it in an interim state between migrations.

! You *might* be able to recover with:   - no dry run output for delete_foreign_key() due to dynamic DDL, sorry

   = ALTER TABLE `desktop_document2` DROP COLUMN `is_trashed` CASCADE; []

 ! The South developers regret this has happened, and would

 ! like to gently persuade you to consider a slightly

 ! easier-to-deal-with DBMS (one that supports DDL transactions)

 ! NOTE: The error which caused the migration to fail is further up.

Error in migration: desktop:0025_auto__add_field_document2_is_trashed
