David Villegas created HADOOP-10962: ---------------------------------------
Summary: Flags for posix_fadvise are not valid in some architectures Key: HADOOP-10962 URL: https://issues.apache.org/jira/browse/HADOOP-10962 Project: Hadoop Common Issue Type: Bug Components: native Affects Versions: 2.4.1 Environment: System z/Linux Reporter: David Villegas In org.apache.hadoop.io.nativeio.NativeIO.java, the posix_fadvise flag parameter is hardcoded to the most common values in fcntl.h. However, not all architectures use the same values (in this case, System z/Linux) A better approach would be to not make assumptions about fcntl.h values (or any other system constants). This bug results in calls to posix_fadvise failing in zLinux. -- This message was sent by Atlassian JIRA (v6.2#6252)
