------------------------------------------------
Summary: AbstractFileInputOperator: During replay, readEntity may
be called without calling openFile.
Key: APEXMALHAR-2268
URL: https://issues.apache.org/jira/browse/APEXMALHAR-2268
Project: Apache Apex Malhar
Issue Type: Bug
Reporter: Munagala V. Ramanath
AbstractFileInputOperator: During replay, if the file named in the recovery
entry is not found, a NPE may be thrown.
Details:
1. In replay(), retryFailedFile() is called.
2. It finds file does not exist and returns null without calling openFile()
3. replay() then continues with the line-reading loop and calls readEntity()
4. readEntity() can throw NPE since the BufferedReader it uses is not
initialized.
