Hi, One of configuration value in your conf/zeppelin-env.sh or conf/zeppelin-site.xml seems "false" which expected to be to a number.
Do you have any environment variable or property set to "false" for the configurations below? ZEPPELIN_PORT, zeppelin.server.port ZEPPELIN_SSL_PORT, zeppelin.server.ssl.port ZEPPELIN_INTERPRETER_CONNECT_TIMEOUT, zeppelin.interpreter.connect.timeout ZEPPELIN_INTERPRETER_MAX_POOL_SIZE, zeppelin.interpreter.max.poolsize ZEPPELIN_INTERPRETER_OUTPUT_LIMIT, zeppelin.interpreter.output.limit Thanks, moon On Fri, Aug 18, 2017 at 2:30 PM Paul Brenner <pbren...@placeiq.com> wrote: > We have a team of 5 users who all use the same zeppelin server.
