The behavior resembles KYLIN-2341. Still worth a new JIRA to track.

There must be another Kylin process still running and holding the lock of
metadata. Find it, kill it, and try again.

You are using wrong version. Please check your HBase version and choose

Kylin maintains three branches for each version: hbase 0.98, hbase 1.x and
cdh 5.7; Please use a hbase 1.x version to start, like
https://github.com/apache/kylin/tree/kylin-1.6.0-HBase1.x

你好，我的主机服务能够正常启动，但是build cube时状态一直停留在PENDING。
[cid:image001.jpg@01D29699.9410D720]
Model的Datasource里同步下来的hive表，Cardinality没有计算出来。
[cid:image002.jpg@01D29699.9410D720]
这可能是什么原因造成的？相关软件的版本信息如下：
Kylin: 1.5.2.1
Hadoop: 2.6.0
Hive: 0.14.0
Zookeeper: 3.4.6
Hbase: 0.98.8
谢谢

sql单独执行没有问题， 在多条并发执行的query后，会爆出来下面的异常
我的java代码：

我的环境是 hadoop 2.7.3 +hbase 1.2.4 +hive 2.1.0 apache-kylin-1.6.0-hbase1.x-bin
KYLIN 自带的 cube 编译的时候到
#17 Step Name: Convert Cuboid Data to HFile 出现错误
我查看了mr 的错误日志，日志如下：请问这个是hadoop 环境问题呢 ，还是 kylin 跟 hbase 版本问题，纠结了很久了，
我同样的一套环境，可以正常通过。请大神指点迷津，万分感觉！！

谢谢 史少锋 ！
还有一个问题，请问我编译源码的时候碰到一个 ，就是不能修改
0.98.8-hadoop2
0.10.0.0
hbase 版本，我hbase 用的是1.2.4当我修改后就编译失败，这个是源码的问题吗？
还是其他问题呢？
我修改 hadoop 跟 Hive版本都可以正常编译的。
