huangsheng created KYLIN-5607:
---------------------------------
Summary: When querying with high concurrency, the query may report
an error (the thread is not safe when ACL permission multi-threaded concurrent
access)
Key: KYLIN-5607
URL: https://issues.apache.org/jira/browse/KYLIN-5607
Project: Kylin
Issue Type: Bug
Components: Metadata
Affects Versions: 5.0-alpha
Reporter: huangsheng
Assignee: huangsheng
Fix For: 5.0-alpha
ACL records are taken out of the cache, and the internal array is modified by
sorting in the init method. Since the metadata in Kylin is shared, there will
be multi-threaded access problems, so there will be concurrent modification
problems here.
