Akira AJISAKA updated HADOOP-12081: ----------------------------------- Resolution: Fixed Fix Version/s: 2.8.0 Status: Resolved (was: Patch Available) I've committed this patch to trunk and branch-2. Thanks [~aroberts] and [~ste...@apache.org] for the reviews. > Fix UserGroupInformation.java to support 64-bit zLinux > ------------------------------------------------------ > > Key: HADOOP-12081 > URL: https://issues.apache.org/jira/browse/HADOOP-12081 > Project: Hadoop Common > Issue Type: Improvement > Components: security > Affects Versions: 2.6.0 > Environment: zLinux > Reporter: Adam Roberts > Assignee: Akira AJISAKA > Labels: zlinux > Fix For: 2.8.0 > > Attachments: HADOOP-12081.001.patch > > > Currently the 64 bit check in security/UserGroupInformation.java uses os.arch > and checks for "64". s390x is returned on IBM's z platform: s390x is 64 bit. > Without this change, if we try to use HDFS with Spark, we get a fatal error > (unable to login as we can't find a login class). > This address fixes said issue by identifying s390x as a 64 bit platform and > thus allowing Spark to run on zLinux. A simple fix with very big implications! -- This message was sent by Atlassian JIRA (v6.3.4#6332)
