add_months.sh now targets a single fat node directly: starts a local Spark cluster via start_spark_cluster.sh, submits jobs, stops the cluster. No salloc needed. add_months_multinode.sh is a new script for the multi-node case using start_spark_and_run.sh from a login node. Usage takes NODES as first arg.

# Multi-node variant of add_months.sh. Uses start_spark_and_run.sh to
|
|
# allocate a Spark cluster across multiple nodes via salloc. Run this
|
|
# from a login node.
|
|
#
|
|
# For the common single-fat-node case, use add_months.sh instead.
|
|
#
|
|
# Usage:
|
|
# add_months_multinode.sh NODES YYYY-MM [YYYY-MM ...]
|
|
#
|
|
# Example (2 nodes, 3 months):
|
|
# add_months_multinode.sh 2 2025-01 2025-02 2025-03
|
|
#
|
|
# Override dump directories via environment variables if needed:
|
|
#
|
|
# COMMENTS_DUMPDIR=/path/to/new/comments \
|
|
# SUBMISSIONS_DUMPDIR=/path/to/new/submissions \
|
|
# ./add_months_multinode.sh 2 2025-01 2025-02
|
|
#
|
|
# NOTE: This script and its workflow are written but not yet tested.
|
|
# Remove this notice after a successful end-to-end run.
