-------------------------------
> Segmentation fault occurs if reindex database when loading data from Hive to
> HAWQ using hcatalog
> ------------------------------------------------------------------------------------------------

> Key: HAWQ-1525
> URL: https://issues.apache.org/jira/browse/HAWQ-1525
> Project: Apache HAWQ
> Issue Type: Bug
> Components: Query Execution
> Reporter: Chunling Wang
> Assignee: Chunling Wang
> Fix For: 2.3.0.0-incubating
>
>
> When we use hcatalog to load data from Hive to HAWQ, if the amount of data is
> big enough, it will trigger automatic statistics collection, calling vacuum
> analyze. At that time if we reindex the database, the system will panic on
> the next auto analyze. Here is the call stack.
