[jira] [Created] (HAWQ-420) Memory leaks in DataLocality during ANALYZE lasting 1 ~ 2 days on 100 nodes cluster.

Hubert Zhang created HAWQ-420:
---------------------------------

             Summary: Memory leaks in DataLocality during ANALYZE lasting 1 ~ 2 days on 100 nodes cluster.
                 Key: HAWQ-420
                 URL: https://issues.apache.org/jira/browse/HAWQ-420
             Project: Apache HAWQ
          Issue Type: Bug
          Components: Core
            Reporter: Hubert Zhang
            Assignee: Lei Chang


On about 100 nodes cluster (SFO), we load data to lineitem and then do ANALYZE on it. It takes 1 ~ 2 days before we cancel the ANALYZE and the QD uses about 48G memory. The major memory consumers are:
```
TopMemoryContext: 48G
----------------------------------------------------------
other: 44G
split_to_segment_mapping_context: 4G
```
