Steven Phillips updated DRILL-3085:
-----------------------------------
Fix Version/s: 1.0.0
> In ExternalSortBatch, Memory Leak in Runtime Generation Code
> ------------------------------------------------------------
>
> Key: DRILL-3085
> URL: https://issues.apache.org/jira/browse/DRILL-3085
> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Codegen
> Reporter: Sean Hsuan-Yi Chu
> Assignee: Sean Hsuan-Yi Chu
> Priority: Critical
> Fix For: 1.0.0
>
>
> This case is related to DRILL-3065.
> In ExternalSortBatch, we have an MSorter to do sorting thing. In this class,
> there are two SelectionVector4, vector4 and aux. If we fail at the time just
> after either gets new memory, the close() method would fail to clean their
> allocated memory properly.
> To reproduce this problem, inject an exception at the last step of
> MSortTemplate.setup()
> Detailed Information:
> 1. Query:
> select n_name from cp.`tpch/nation.parquet` order by n_name
> *. Using this query alone cannot help reproduce the issue. We still need to
> inject the exception at the right place.
> 2. Data:
> cp.`tpch/nation.parquet`
> 3. Log:
> java.lang.IllegalStateException: Failure while closing accountor. Expected
> private and shared pools to be set to initial values. However, one or more
> were not. Stats are
> zone init allocated delta
> private 0 0 0
> shared 3221225472 3195686243 25539229.
