[jira] [Commented] (FALCON-1195) ClusterEntityParserTest fails intermittently

["Balu Vellanki (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FALCON-1195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14529220#comment-14529220 ] 

Balu Vellanki commented on FALCON-1195:
---------------------------------------

The error happens because testClusterWithSubdirInStaging() can potentially run before testClusterWithOnlyStaging(). Test testClusterWithSubdirInStaging()  creates "/projects/falcon/staging/working" dir with 777 permissions.  Falcon code does not create the working dir if it already exists, hence testClusterWithOnlyStaging() is unable to create "/projects/falcon/staging/working" with 755 permissions.

The solution is to use a different name for staging/working dirs for each test. This should completely avoid the race condition.
