[jira] [Commented] (FALCON-428) Unable to start both prism and
falcon server from same installation directory
[ https://issues.apache.org/jira/browse/FALCON-428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13988102#comment-13988102 ]
Satish Mittal commented on FALCON-428:
--------------------------------------
>From logs, it appears the error occurs because of failure to initialize MetadataMappingService.

{noformat}
As part of initializing MetadataMappingService, Titan graph factory open initializes its BerkeleyJEStoreManager which tries to acquire single writer access lock over the file system by creating je.lck file. However the first server has already created .lck file at same location by this time.
