Log synchronization to ODPS fails with the error "readLog fail, logFile not exists"
Log export to ODPS fails with the error "readLog fail, logFile not exists" when you use Log Management > standard log export in the mPaaS Mobile Analytics console.
The logs are successfully synced to mPaaS and can be queried on the Mobile Analytics > Log Management > Log Playback page in the mPaaS console, but exporting them to ODPS fails.
This issue is caused by insufficient ODPS authorization. Verify that you have the permissions to read table metadata (Describe) and table data (Select). If either permission is missing, grant the authorization as shown in the following figure, and then retry the standard log export.
The following figure shows an example of granting the "worker" role permission to read metadata and data for the "shop_name" and "customer_id" columns in the "sale_detail" table.
