-------------------------------------
Summary: Cannot create Plasma object after OutOfMemory error
Key: ARROW-5560
URL: https://issues.apache.org/jira/browse/ARROW-5560
Project: Apache Arrow
Issue Type: Bug
Components: C++ - Plasma
Affects Versions: 0.13.0
Reporter: Stephanie Wang
Fix For: 0.13.0
If the client tries to call `CreateObject` and there is not enough memory left
in the object store to create it, an `OutOfMemory` error will be returned.
However, the plasma store also creates an entry for the object, even though it
failed to be created. This means that later on, if the client tries to create
the object again, it will receive an error that the object already exists.
Also, if the client tries to get the object, it will hang because the entry
appears to be unsealed.
We should fix this by only creating the object entry if the `CreateObject`
operation succeeds.
