-----------------------------------------
Summary: Failed to restart application on MapR
Key: APEXCORE-590
URL: https://issues.apache.org/jira/browse/APEXCORE-590
Project: Apache Apex Core
Issue Type: Bug
Reporter: Pradeep A. Dalvi
Assignee: Pradeep A. Dalvi
For restarting application, we try to copy previous app state i.e. checkpoints
directory from original app. Before doing so, we try to delete 'checkpoints'
directory from newly launched application directory. MapR-FS throws an
exception since that directory is not present yet, hence we fail to copy
checkpoints from original app.
Need to catch exception around fs.delete(checkpointPath, true); in
copyInitialState function of StramClient.
