snappuller has limitation w/r/t/ handling multiple web apps
-----------------------------------------------------------
Key: SOLR-524
URL: https://issues.apache.org/jira/browse/SOLR-524
Project: Solr
Issue Type: Improvement
Components: replication
Affects Versions: 1.2
Environment: Linux (CentOS release 5 (Final))
Java JDK 6
Reporter: Ezra Epstein
Priority: Minor
The snappuller has a limitation which makes it hard to use for replicating the
indices for multiple webapps. In particular, by changing:
# rsync over files that have changed
rsync -Wa${verbose}${compress} --delete ${sizeonly} \
${stats} rsync://${master_host}:${rsyncd_port}/solr/${name}/
${data_dir}/${name}-wip
to:
# rsync over files that have changed
rsync -Wa${verbose}${compress} --delete ${sizeonly} \
${stats} rsync://${master_host}:${rsyncd_port}/${rsync_module_path}/${name}/
${data_dir}/${name}-wip
and adding an rsync_module_path variable to scripts.conf, plus giving it a
default value of "solr" before the 'unset' commands at the top of the
snappuller script, I've worked around the issue. Still, it seems better to not
hard-code the module name ([solr]) and also to allow some flexibility in the
location of the data files under that module. This is req'd for multiple
webapps since they won't share a data folder.
