----------------------------------
Summary: Option to pass solr.hdfs.home in API backup/restore calls
Key: SOLR-14507
URL: https://issues.apache.org/jira/browse/SOLR-14507
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: Backup/Restore
Reporter: Haley Reeve
The Solr backup/restore API has an optional parameter for specifying the
directory to backup to. However, the HdfsBackupRepository class doesn't use
this location when creating the HDFS Filesystem object. Instead it uses the
solr.hdfs.home setting configured in solr.xml. This functionally means that the
backup location, which can be passed to the API call dynamically, is limited by
the static home directory defined in solr.xml. This requirement means that if
the solr.hdfs.home path and backup location don't share the same URI scheme and
hostname, the backup will fail, even if the backup could otherwise have been
written to the specified location successfully.
If we had the option to pass the solr.hdfs.home path as part of the API call,
it would remove this limitation on the backup location.
