# List Hive tables in all databases via beeline
|
|
#
|
|
# Tested on Hive 1.1.0 on CDH 5.10, 5.16
|
|
|
|
# For Hive 3.0+ information schema is finally available which is more efficient than iterating per database eg.
|
|
#
|
|
# SELECT * FROM information_schema.tables
|
|
# (table_catalog, table_schema, table_name)
|
|
|
|
# you will need to comment out / remove '-o pipefail' below to skip errors if you aren't authorized to use
|
|
# any of the databases to avoid the script exiting early upon encountering any authorization error such:
|
|
#
|
|
# ERROR: AuthorizationException: User '<user>@<domain>' does not have privileges to access: default Default Hive database.*.*
|
|
