Abid Mohammed created STORM-2095:
------------------------------------
Summary: Nimbus dies and never recovers due to
java.nio.file.DirectoryNotEmptyException
Key: STORM-2095
URL: https://issues.apache.org/jira/browse/STORM-2095
Project: Apache Storm
Issue Type: Bug
Components: blobstore
Affects Versions: 1.0.0, 1.0.1, 1.0.2, 1.1.0, 1.0.3
Reporter: Abid Mohammed
Priority: Critical
To Recreate:
--------------------------------------
1) Create a blobstore key for a large file (1 or 2 GB). Size of the file does
not matter if nimbus can be killed while the blob is being created.
2) while the blob is being created, restart nimbus (this is easiest way to
regenerate, there can be various reasons due to which a blob couldn't be
successfully created in nimbus)
3) When nimbus tries to start on restart, it will keep dying due to
DirectoryNotEmptyException and never come up.
Expected Behavior
--------------------------------------
Partial blobstore key is deleted cleanly and doesn't affect nimbus.
The actual, incorrect behavior.
