MapReduce Problems with Snappy on HDP 2.06 Update to 2.2

  • #45667

    I installed HDP with Update to Hadoop 2.2 with snappy (from hdp-utils on SUSE Linux Enterprise Server – Service Pack 3 according to instruction on HDP-Documentation “Installing HDP Manually” 10/22/2013
    During the execution of a MapReduce-Job, which takes up an snappy-compressed file, the following error occured:

    Error: org.apache.hadoop.util.NativeCodeLoader.buildSupportsSnappy()Z

    I’ve tried the HDP-Sandbox (CentOS 6.4 based) for VirtualBox too, but there isn’t snappy installed or configured.
    What’s going wrong?
    I’ve also had run the MR-Job with DEBUG option, but only the Error-Message above was displayed.
    Next try was installation of Hadoop tar-ball (HDFS/MR) from Apache and there the MR-Job is working well.
