Derek Tapley created ZEPPELIN-3881:
--------------------------------------
Summary: Adding BigDL as a dependency to Spark interpreter causes
indefinite pending cells, UI instability.
Key: ZEPPELIN-3881
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3881
Project: Zeppelin
Issue Type: Bug
Components: GUI, Interpreters, zeppelin-server
Affects Versions: 0.8.0, 0.7.3
Environment: Environment 1: Zeppelin 0.7.3 via HDP 2.6.5 on Centos 7
Environment 2: Zeppelin 0.8.0 on Ubuntu 14.04 via Docker
Reporter: Derek Tapley
Fix For: 0.8.1
Adding BigDL version 0.7.0 via Maven Central to the default Spark interpreter
seems to cause behind-the-scenes stability issues. Although no errors are
given on the Interpreters page after adding the dependency, attempting to run a
%spark paragraph with even trivial expressions (val x = 1) results in an
indefinitely pending cell. Attempting to restart the interpreter results in
nothing, and (usually) loading other notebooks no longer becomes possible.
After checking both the interpreter and zeppelin server log files, I couldn't
find any lines pertaining to why those paragraphs are pending indefinitely.
