HDP on Linux – Installation Forum

Native snappy library not available

  • #28052

    I am using HDP 1.3, installed snappy library using command “yum install snappy snappy-devel”
    Also I am using jdk 1.6_45 (32bit), so link “ln -sf /usr/lib64/ /usr/lib/hadoop/lib/native/Linux-i386-32/” was created.

    Folder /usr/lib/hadoop/lib/native/Linux-i386-32 contains:
    lrwxrwxrwx 1 root root 23 Jun 23 17:24 -> /usr/lib64/

    When I am running example: “/usr/lib/hadoop/bin/hadoop jar /usr/lib/hadoop/hadoop-examples.jar terasort /test/10gsort/input /test/10gsort/output”

    I get exception:
    13/06/23 17:43:30 INFO mapred.JobClient: Task Id : attempt_201306231742_0001_m_000000_0, Status : FAILED

    Please assist.
