because wrong Path
Key: KYLIN-3782
URL: https://issues.apache.org/jira/browse/KYLIN-3782
Project: Kylin
Issue Type: Bug
Components: Storage - HBase
Affects Versions: v2.6.0
Reporter: hailin.huang
Fix For: v2.6.1
In my windows env, when I run kylin, Kylin service can't start. In class
ZookeeperDistributedLock, I found kylin use File(path).getCanonicalPath() to
norm windows path, however this will get a path like '
C:\kylin\kylin_metadata1\job_engine\global_job_engine_lock', for zookeeper,Path
must start with / character.
Below is stackTrace:
