PositionCache decrements its position for reads at the end of file
------------------------------------------------------------------
Key: HADOOP-42
URL: http://issues.apache.org/jira/browse/HADOOP-42
Project: Hadoop
Type: Bug
Components: fs
Reporter: Konstantin Shvachko
Attachments: Position.patch
See
int org.apache.hadoop.fs.FSDataInputStream.PositionCache.read(byte[] b, int
off, int len)
if in.read() returns -1 (e.g. at the end of file) the position in the cache
will be decremented, while it should be retained.
The attached patch would fix it.
