Hudson commented on HADOOP-8614: -------------------------------- Integrated in Hadoop-Hdfs-trunk #1141 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/1141/]) HADOOP-8614. IOUtils#skipFully hangs forever on EOF.

However, I looked at both InputStream#skip and > ByteArrayInputStream#skip, and they both simply return 0 on EOF (no > exception). So it seems safe to assume that this is the standard Java way of > doing things in an InputStream. > Currently IOUtils#skipFully will loop forever if you ask it to skip past EOF! -- This message is automatically generated by JIRA.
