Hudson commented on HDFS-6071: ------------------------------ SUCCESS: Integrated in Hadoop-trunk-Commit #5294 (See [https://builds.apache.org/job/Hadoop-trunk-Commit/5294/]) HDFS-6071. BlockReaderLocal does not return -1 on EOF when doing a zero-length read on a short file.

Specifically, if the file is shorter than the readahead buffer, > or if the position is nearer to the end than the length of the readahead > buffer, this may happen. This is mainly a concern because libhdfs relies on > this to determine whether it should use direct reads. -- This message was sent by Atlassian JIRA (v6.2#6252)
