[jira] [Commented] (IOTDB-1191) [Zeppelin-IoTDB]Exception in thread
"main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
[ https://issues.apache.org/jira/browse/IOTDB-1191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17297888#comment-17297888 ]
Rong Kang commented on IOTDB-1191:
----------------------------------
Hi, it's most likely because the zeppelin-iotdb-interpreter doesn't involve package dependencies. This problem has been resolved in [PR-2299|https://github.com/apache/iotdb/pull/2299].
You can check the file size of the zeppelin-iotdb-interpreter. A usable interpreter that I packaged is about {color:#FF0000}9.1M{color}, while an unusable one is only {color:#FF0000}800K{color}.
