[jira] Commented: (HADOOP-2931) exception in DFSClient.create:
Stream closed
[ https://issues.apache.org/jira/browse/HADOOP-2931?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12574738#action_12574738 ]
Michael Bieniosek commented on HADOOP-2931:
-------------------------------------------
Okay, it seems that java sets the stacktrace when the exception is created, and not when the exception is thrown. So this is really just a bad error message masking the true error.
