----------------------------------------
Summary: Suggester BlendedInfixLookupFactory to support HDFS store
for indexwriter
Key: SOLR-11194
URL: https://issues.apache.org/jira/browse/SOLR-11194
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: Suggester
Affects Versions: 6.6
Reporter: Peter Szantai-Kis
Priority: Minor
When relative path is used for indexPath in the LookupFactory, the solr cores
DataDir is used as a prefix, but still will be created in the working directory
of the process. Unfortunately both the BlendedInfixLookupFactory and it's
parent AnalyzingInfixLookupFactory uses a store implementation that does not
support HDFS. So in case the data dir is on hdfs then the "hdfs:/" prefix will
be ignored and because of the missing leading forward slash it will be treated
as a relative path. It seems hdfs wasn't really considered as an option when
these Suggesters were implemented.
One possible solution is to use the SolrCores' own DirectoryFactory to lookup
the data dir which dynamically will return the proper store in case of HDFS is
used
