Creating Symbolic Links for the Library Files in the Region Servers

Creating Symbolic Links for the Library Files in the Region Servers

You must copy the required library files to each region server that stores data. You must then create symbolic links for the copied library files in the appropriate directories of the region servers so that the region servers can perform the searches.
  1. Copy the following
    .so
    and
    .JAR
    files to a region server:
    • /usr/local/mdmbdrm-<Version Number>/libjssan3clex.so
    • /usr/local/mdmbdrm-<Version Number>/libssan3v2.so
    • /usr/local/mdmbdrm-<Version Number>/libssan3tb.so
    • /usr/local/mdmbdrm-<Version Number>/libssan3cl.so
    • /usr/local/mdmbdrm-<Version Number>/libssalsn.so
    • /usr/local/mdmbdrm-<Version Number>/libssaiok.so
    • /usr/local/mdmbdrm-<Version Number>/libjssan3cl.so
    • /usr/local/mdmbdrm-<Version Number>/bin/ssan3.jar
  2. Create symbolic links for the
    .so
    files in the following directory of the region server:
    $HADOOP_HOME/lib/native
    The following sample command creates symbolic links in the
    $HADOOP_HOME/lib/native
    directory for all the
    .so
    files:
    ln -s /usr/local/mdmbdrm-10.0/bin/*.so /usr/lib/hadoop/lib/native/
  3. Create symbolic link for the
    ssan3.jar
    file in the following directory of the region server:
    $HBASE_HOME/lib/
    The following sample command creates symbolic link in the
    $HBASE_HOME/lib/
    directory for the
    ssan3.jar
    file:
    ln -s /usr/local/mdmbdrm-10.0/bin/ssan3.jar /usr/lib/hbase/lib
  4. Copy the population files to the same directory that you configured for the
    ssapr
    parameter of the configuration file in the region server.
    For example, if
    ssapr=/usr/local/mdmbdrm-10.0/population
    , create the same directory structure in the region server and copy the population files to the
    population
    directory.
