# Show table location for all tables via Impala shell
#
# FILTER environment variable will restrict to matching fully qualified tables (<db>.<table>)
#
# Caveats:
#
#     Hive is more reliable as Impala breaks on some table metadata definitions where Hive doesn't
#
#     Impala is faster than Hive for the first ~1000 tables but then slows down
#     so if you have a lot of tables I recommend you use the Hive version of this instead
#
# Tested on Impala 2.7.0, 2.12.0 on CDH 5.10, 5.16 with Kerberos and SSL
#
# For more documentation see the comments at the top of impala_shell.sh

# For a better version written in Python see DevOps Python tools repo:
#
# https://github.com/harisekhon/devops-python-tools

# you will almost certainly have to comment out / remove '-o pipefail' to skip authorization errors such as that documented in impala_list_tables.sh
set -eu  # -o pipefail
