------------------------------------

             Summary: SuggestionHelper creating unnecessary temporary directories
                 Key: OAK-3917
                 URL: https://issues.apache.org/jira/browse/OAK-3917
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: lucene
            Reporter: Chetan Mehrotra
             Fix For: 1.4


SuggestHelper create a temporary directory [1] mostly likely as a workaround to allow use
of {{OakDirectory}}. With time this can grow unbounded (as dir is not cleaned) and following
exception is seen.
