I had a thread regarding this in the user group and I was able to
workaround on 0.6.1 build by setting SPARK_HOME. As there is no workaround
in latest snapshot build, I'm sending this to the dev group. You may need
to have a secure(kerberos) cluster behind a proxy to reproduce these
inconsistencies/issues with spark interpreter.
*0.7 latest Snapshot:* When I git clone & build the 0.7 snapshot and run
spark interpreter in local mode after copying hive_site.xml to conf
directory with just one HADOOP_CONF_DIR property set in zeppelin-env.sh,
I'm able to run a spark paragraph to test the interpreter, but it doesn't
talk to my cluster, it runs in a standalone mode and shows only "default"
database when executing *z.show(sql("show databases"))*. *Now when I set
the SPARK_HOME variable in zeppelin-env.sh and restart, I get the stack
trace cascaded below.*
*0.6.1 build: *When I download the 0.6.1 source and run spark interpreter
in local mode after copying hive_site.xml to conf directory with just one
HADOOP_CONF_DIR property set in zeppelin-env.sh, I'm able to run a
spark paragraph to test the interpreter, but it doesn't talk to my cluster,
it runs in a standalone mode and shows only "default" database when
executing *z.show(sql("show databases"))*. *Now when I set the SPARK_HOME
variable in zeppelin-env.sh and restart, the spark interpreter is able to
talk to my cluster and show all my databases in the cluster*
*0.5.6 build *When I download the 0.5.6 source and run spark interpreter in
local mode after copying hive_site.xml to conf directory with just one
HADOOP_CONF_DIR property set in zeppelin-env.sh, I'm able to run a
spark paragraph to test the interpreter, *and it talks to my cluster
without even setting "SPARK_HOME" environment variable where I can see all
my databases when executing **z.show(sql("show databases"))*
