Subject [jira] [Commented] (HAMA-258) Design a input and output system
Date Sat, 06 Aug 2011 10:19:27 GMT

    [ https://issues.apache.org/jira/browse/HAMA-258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13080393#comment-13080393
] 

ChiaHung Lin commented on HAMA-258:
-----------------------------------

When testing to replace the code that launches BSPPeer child by TaskRunner with another thread,
I observed in the example SerilaizePrinting where printOutput() tries to print data written
in the stage of writeLogToFile() may have race condition, resulting in the printOutput()is
executed earlier than writeLogToFile(); thus FileNotFoundException is thrown. Probably we
will need to provide api which encapsulates the coordination between the client and bsp server
program.
