SPARK_PROFILE=1.4 SPARK_VERSION=1.4.1 HADOOP_PROFILE=2.4 HADOOP_VERSION=2.4.0 curl -sL --retry 3 \ " http://mirrors.ibiblio.org/apache/spark/spark-$SPARK_VERSION/spark-$SPARK_VERSION-bin-hadoop$HADOOP_PROFILE.tgz"; \ | gunzip \ | tar x -C /usr/ \ && ln -s /usr/spark-$SPARK_VERSION-bin-hadoop$HADOOP_PROFILE /usr/spark \ && rm -rf /usr/spark/examples \ && rm /usr/spark/lib/spark-examples*.jar and then in my zeppelin configuration file I have this: export SPARK_HOME="/usr/spark" 2015-11-08 7:09 GMT+01:00 moon soo Lee <m...@apache.org>: > This error may able to occur when SparkContext got some error to connect > to Spark cluster. > > Could you share how you configured Zeppelin? > Have you export SPARK_HOME and set 'master' property in 'Interpreter' page? > > Thanks, > moon > > > On Fri, Nov 6, 2015 at 1:03 AM Bill Sparks <jspa...@cray.com> wrote: > >> Hello. >> >> I'm trying to run the master branch on CentOS6.5. >> >> My compile completes and the server start successfully, in the log file I >> see the following warnings.
