Hue Error – DatabaseError: database is locked
January 20, 2016 Leave a comment
You may face this error in Hue while using Impala or Hive. This is because of the lock happening in the backend database used in Hue. Hue uses a backend database to store all the metadata and history. By default it uses sqlite, which is not suitable for multiuser environments. The usage of the sqlite causes this issue.
We can resolve this by using mysql, postgresql or oracle database as the metastore for hue.
