Subject [jira] Commented: (HBASE-3038) WALReaderFSDataInputStream.getPos() fails if Filesize > MAX_INT
Date Fri, 07 Jan 2011 21:24:46 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3038?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12978970#action_12978970
] 

Nicolas Spiegelberg commented on HBASE-3038:
--------------------------------------------

this is only being called on the first invocation, which is the SequenceFile.Reader constructor.

{code}
         if (this.firstGetPosInvocation) {
           this.firstGetPosInvocation = false;
           ...
{code}

> WALReaderFSDataInputStream.getPos() uses  this.in.available() to determine the actual
length of the file.  Except that available() returns an int instead of a long.  Therefore,
our current logic is broke when trying to read a split log > 2GB.
