some steps:
.1 find the different global_dictionary rowkey in segment 
.2 you should delete the segment first
.3 delete the rowkey in Hbase tables which start with '/dict' and '/cube'

Subject: GlobalDict should have 0 or 1 append dict but 2?
Hi all,
   I build a cube with a column named “USER_ID” using global dictionary day 
by day. Last day I met a problem that this column has 2 global dictionary like :
In this pic , DW.INCR_D_USER_NEW_CHANNEL is the hive table name.
 
I found that the dictionary ID of USER_ID in last segments is different from 
other segments:
 
 
so my idea is delete the last segment and rebuild it , but I don’t know  how to 
do it.
I found there is an rest-api in 
https://issues.apache.org/jira/browse/KYLIN-1540 but is’t not in the kylin 
official doc. Is this api working ? if so , someone can give me a example？
 
I also found a solution in 
http://apache-kylin.74782.x6.nabble.com/Re-more-than-1-append-dict-for-globalDict-td7028.html
 but it’s useless for me because I can not login cluster as Hadoop 
administrator,I just have the admin privilege of kylin.
I wondering if there is a solution without using Hadoop cmd.
 
 
In the above solution, I can’t not find how this error happened and I want know 
it.
 
Thanks!
 
 
Best wishes,
Light

Could you prepare the code which could reproduce the issue?

kylin 无法加载hive classpath 内得lib

[wu lihu]

Hi All
我是用得 AWS EMR， 我把JSON-SERDE 得 jar 加入了 hive 得 classpath 里面了，修改了
find-hive-dependency.sh ，把这个JAR 得路径也加入进去了。可是还是加载不了 hivemeta  报错
 Caused by: MetaException(message:java.lang.ClassNotFoundException
Class org.openx.data.jsonserde.JsonSerDe not found)

但是我在 System tab 里面可以看到
/usr/lib/hive/lib/json-serde-1.3.8-SNAPSHOT-jar-with-dependencies.jar
在classpath 里面。 请问这个怎么解决？
