My .so file has other .so dependencies , so would I have to add them all in the DistributedCache . Also I tried setting LD_LIBRARY_PATH in mapred-site.xml as
<property> <name>mapred.child.env</name> <value>LD_LIBRARY_PATH=/opt/libs/</value> </property> doesnt work. the java.library.path is not sufficient to set , have to get LD_LIB set. -Utkarsh On Thu, Feb 18, 2010 at 3:14 PM, Allen Wittenauer <[email protected]>wrote: > > > Like this: > > > http://hadoop.apache.org/common/docs/current/native_libraries.html#Loading+n > ative+libraries+through+DistributedCache > > > > On 2/16/10 5:29 PM, "Jason Rutherglen" <[email protected]> wrote: > > > How would this work? > > > > On Fri, Feb 12, 2010 at 10:45 AM, Allen Wittenauer > > <[email protected]> wrote: > >> > >> ... or just use distributed cache. > >> > >> > >> On 2/12/10 10:02 AM, "Alex Kozlov" <[email protected]> wrote: > >> > >>> All native libraries should be on each of the cluster nodes.
