-----------------------------------
Component/s: Functions - Drill
> Memory leak in kvgen function
> -----------------------------
>
> Key: DRILL-1787
> URL: https://issues.apache.org/jira/browse/DRILL-1787
> Project: Apache Drill
> Issue Type: Bug
> Components: Functions - Drill
> Reporter: Jason Altekruse
> Assignee: Jason Altekruse
> Fix For: 0.7.0
>
>
> Running a kvgen on a map with large values will produce a memory leak. This is due to improper use of the reallocIfNeeded() method on DrillBuf. This method returns a new buffer, it does not resize the buffer within the one that is calling the method. This buffer is automatically freed by the method itself, so a reference just needs to be saved in the same variable holding the original buffer.
> Error message produced is standard memory leak error in Drill, pasted below.
> Query failed: Failure while running fragment., Attempted to close accountor with 6 buffer(s) still allocatedfor QueryId: 64a39e3c-42a9-455d-aaee-0c7374492835, MajorFragmentId: 0, MinorFragmentId: 0.
