Thiruvalluvan M. G. updated AVRO-524: ------------------------------------- Status: Patch Available (was: Open) > DataFileWriter.appendTo leads to intermittent IOException during write() > ------------------------------------------------------------------------ > > Key: AVRO-524 > URL: https://issues.apache.org/jira/browse/AVRO-524 > Project: Avro > Issue Type: Bug > Components: java > Reporter: Thiruvalluvan M. G. > Assignee: Thiruvalluvan M. G. > Fix For: 1.4.0 > > Attachments: AVRO-524.patch > > > To append to a data file, we first open the file as RandomAccessFile in > read-write mode, read some information such sync, seek to the end of the file > and then use its FileDescriptor to create a FileOutputStream. Sharing a > FileDescriptor this way could lead to problem if one of its containers is > garbage-collected while the other is still in use. Please see: > http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6322678. The bug got fixed > in Java 7 (b06). In our case, RandomAccessFile sometimes gets > garbage-collected leading to write errors. If the Java unit-tests are run > multiple times, this occurs about 25% of the time on my Windows machine and > about 50% on my Ubuntu Linux box. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
