[jira] Updated: (HADOOP-2071) StreamXmlRecordReader throws
java.io.IOException: Mark/reset exception in hadoop 0.14
[ https://issues.apache.org/jira/browse/HADOOP-2071?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
lohit vijayarenu updated HADOOP-2071:
-------------------------------------
Attachment: HADOOP-2071-1.patch
Attached is a patch, which eliminates mark/reset.
At one place seek() was called even after reset() which made it redundant.
Please could anyone review this.
Thanks
