Subject [jira] [Commented] (YARN-2377) Localization exception stack traces are not passed as diagnostic info
Date Sat, 13 Sep 2014 22:11:35 GMT

    [ https://issues.apache.org/jira/browse/YARN-2377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14132994#comment-14132994

Gera Shegalov commented on YARN-2377:
-------------------------------------

Hi [~Naganarasimha], there is no deserialization in a sense of converting bytes to the original
exception class. This fields are already strings in yarn_protos.proto:
{code}
 33 message SerializedExceptionProto {                                              
 34   optional string message = 1;                                                  
 35   optional string trace = 2;                                                    
 36   optional string class_name = 3;                                               
 37   optional SerializedExceptionProto cause = 4;                                  
 38 }
{code}
