[jira] [Created] (KYLIN-4333) Build Server OOM

wangxiaojing created KYLIN-4333:
-----------------------------------

             Summary: Build Server OOM
                 Key: KYLIN-4333
                 URL: https://issues.apache.org/jira/browse/KYLIN-4333
             Project: Kylin
          Issue Type: Improvement
          Components: Job Engine, Query Engine
    Affects Versions: v3.0.0-alpha2, v3.0.0-beta, v3.0.0
            Reporter: wangxiaojing


Kylin 3 frequently appears full GC or even OOM, and build server appears OOM almost every 4 days. Query server also has full GC, but it appears less frequently than build server.

We have about 2000 cubes on this Kylin cluster (3 build servers and 3 query servers , 32g memory per server)。

Through mat analysis of dump, there may be a memory leak.
